Test method Principle Applicable heat-treated parts Characteristics Remarks

1. Brinell hardness

・ A ball indenter （steel or carbide alloy） is used to indent the test surface. Hardness is given by dividing the test load by the surface area, which was found from the diameter of the indentation.

・Annealed parts・Normalized parts・Anchored materials

① Suitable for uneven materials and forged products because the indent is large.

②�Not suitable for small or thin specimens

JIS Z 2243

2. Rockwell hardness

・ The standard or test load is applied via a diamond or ball indenter, and the hardness value is read from the tester.

・Hardened parts and tempered parts・Carburized surfaces・Nitrided surfaces・�Thin sheets of copper, brass,

bronze, or similar materials※ Rockwell C scale （HRC） is not suitable for

materials such as narrow pins and thin sheets.

① Hardness value can be obtained quickly.② Suitable as an intermediate test

of actual products③ Caution is required because

there are many types.※ There are many types of Rockwell hardness

testers, including the A scale （HRA）, B scale （HRB）, C scale （HRC）, and D scale （HRD）.

JIS Z 2245

3. Shore hardness

・ The specimen is set on a table and a hammer is dropped from a set height. Hardness is determined based on how high the hammer bounces.

・�Hardened parts and tempered parts・Nitrided parts・�Large parts treated by carburizing

or similar process

① Extremely easy to operate. Data can be obtained quickly.

② Suitable for large parts③ Because indent is small and not

noticeable, this test is suitable for actual products.

④ Compact and light-weight. Portable.

JIS Z 2246

4. Vickers hardness

・ A diamond square pyramid indenter with a vertex angle of 136 degrees is used to create an indentation in the test surface. The hardness value is found from the test load and the surface area of the indent, computed from the length of the diagonal lines of the indent. （Conversion is performed automatically.）

・ Materials with a thin hardened layer created by induction hardening, carburizing, nitriding, electroplating, ceramic coating, etc.・�Hardened layer depth in

carburized and nitrided parts

① Suitable for small and thin specimens

② Because the indenter is diamond, this test can be used with materials of any hardness.

Test method Principle Applicable heat-treated parts Characteristics Remarks

1. Brinell hardness

・ A ball indenter （steel or carbide alloy） is used to indent the test surface. Hardness is given by dividing the test load by the surface area, which was found from the diameter of the indentation.

・Annealed parts・Normalized parts・Anchored materials

① Suitable for uneven materials and forged products because the indent is large.

②�Not suitable for small or thin specimens

JIS Z 2243

2. Rockwell hardness

・ The standard or test load is applied via a diamond or ball indenter, and the hardness value is read from the tester.

・Hardened parts and tempered parts・Carburized surfaces・Nitrided surfaces・�Thin sheets of copper, brass,

bronze, or similar materials※ Rockwell C scale （HRC） is not suitable for

materials such as narrow pins and thin sheets.

① Hardness value can be obtained quickly.② Suitable as an intermediate test

of actual products③ Caution is required because

there are many types.※ There are many types of Rockwell hardness

testers, including the A scale （HRA）, B scale （HRB）, C scale （HRC）, and D scale （HRD）.

JIS Z 2245

3. Shore hardness

・ The specimen is set on a table and a hammer is dropped from a set height. Hardness is determined based on how high the hammer bounces.

・�Hardened parts and tempered parts・Nitrided parts・�Large parts treated by carburizing

or similar process

① Extremely easy to operate. Data can be obtained quickly.

② Suitable for large parts③ Because indent is small and not

noticeable, this test is suitable for actual products.

④ Compact and light-weight. Portable.

JIS Z 2246

4. Vickers hardness

・ A diamond square pyramid indenter with a vertex angle of 136 degrees is used to create an indentation in the test surface. The hardness value is found from the test load and the surface area of the indent, computed from the length of the diagonal lines of the indent. （Conversion is performed automatically.）

・ Materials with a thin hardened layer created by induction hardening, carburizing, nitriding, electroplating, ceramic coating, etc.

・�Hardened layer depth in carburized and nitrided parts

① Suitable for small and thin specimens

② Because the indenter is diamond, this test can be used with materials of any hardness.

Symbol Meaning Diagram

Direction of grains left by the cutting instrument are parallel to the projection plane of the drawing where the symbol is entered. Example: Shaped surface

Direction of grains left by the cutting instrument are perpendicular to the projection plane of the drawing where the symbol is entered. Examples: Shaped surface

（side view）, circular cut, cylindrical cut

Direction of grains left by the cutting instrument intersect in 2 directions at angles to the projection plane of the drawing where the symbol is entered. Example: Honed surface

Direction of grains left by the cutting instrument intersect in multiple directions or have no direction. Examples: Lapped surface, superfinished

surface, and surface finished by front milling or end milling with cross feed

Grains left by the cutting instrument are virtually concentric around the center of the projection plane of the drawing where the symbol is entered. Example: Facing surface

Grains left by the cutting instrument are virtually radial with respect to the center of the projection plane of the drawing where the symbol is entered.

Arithmetical average roughness （Ra）A portion stretching over a reference length in the direction in which the average line extends is cut out from the roughness curve. This portion is presented in a new graph with the X axis extending in the same direction as the average line and the Y axis representing the magnitude. When the roughness curve is represented by y＝f（χ）, Ra is the value in microns （µm） found from the formula shown at right.

Maximum height （Ry）A portion stretching over a reference length in the direction in which the average line extends is cut out from the roughness curve. The gap between the peak line and valley line in this portion is measured in the direction of the magnitude axis, and this value is indicated in microns （µm）. Note: When finding Ry, the reference length is selected from a portion which contains no

abnormally high peaks or abnormally low valleys （locations which are likely flaws）.

Ten-spot average roughness （Rz）A portion stretching over a reference length in the direction in which the average line extends is cut out from the roughness curve.

■Types and symbols of geometrical tolerances

The meanings of the lines used in the drawings in the “definition of tolerance range” column are as follows.Thick solid or broken line: Shape Thin dash-dot line: Center line Thick dash-dot line: DatumThin alternating long and two short dashes line: Supplementary projection plane or section plane Thin solid or broken line: Tolerance range Thick alternating long and two short dashes line: Projection of shape onto supplementary plane or section plane

If a tolerance frame is connected to a dimension that indicates the diameter of a cylinder, the axis line of the cylinder shall be contained within a cylinder of 0.08mm diameter.

If the symbol φ is attached before the numerical value that indicates the tolerance range, this tolerance range is the range within a cylinder of diameter t.

This surface shall be contained within two parallel planes separated by 0.08mm.

The tolerance range is the area between two parallel planes separated by distance t.

The circumference in any section normal to the axis shall be contained between two concentric circles separated by 0.1mm on the same plane.

The tolerance range in the considered plane is the area between two concentric circles separated by distance t.

The considered surface shall be contained between two coaxial cylinder surfaces separated by 0.1mm.

The tolerance range is the range contained between two coaxial cylinder surfaces separated by distance t.

In any cross-section parallel to the projection plane, the considered profile shall be contained between the two envelope curves formed by a 0.04mm diameter circle, the center of which is situated on the theoretically correct profile curve.

The tolerance range is the range contained between the two envelope curves formed by a circle with diameter t, the center of which is situated on the theoretically correct profile curve.

The considered surface shall be contained between the two enveloping surfaces formed by a 0.02mm diameter sphere, the center of which is situated on the surface containing the theoretically correct profile.

The tolerance range is the range contained between the two enveloping surfaces formed by a sphere with diameter t, the center of which is situated on the theoretically correct profile surface.

The surface shown by the arrow of the indicator line shall be contained between two planes parallel to the datum plane A and separated by 0.01mm in the direction of the arrow of the indicator line.

The tolerance range is the range contained between two planes parallel to the datum plane and separated by distance t.

The axis of the cylinder shown by the arrow of the indicator line shall be contained within a cylinder of diameter 0.01mm that is perpendicular to the datum plane A.

If symbol φ is attached before the numerical value indicating the tolerance range, this tolerance range is the range contained within a cylinder of diameter t that is perpendicular to the datum plane.

The surface shown by the arrow of the indicator line shall be contained between two parallel planes which are inclined with theoretical exactness by 40 degrees to the datum plane A, and which are separated by 0.08mm in the direction of the arrow of the leader line.

The tolerance range is the range contained between two parallel planes inclined at a specified angle to the datum plane and separated from each other by distance t.

The point shown by the indicator line shall be contained within a 0.03mm diameter circle with its center situated at the true location 60mm from datum line A and 100mm from datum line B.

The tolerance range is the range contained within a circle or sphere of diameter t with its center situated at the theoretically exact location of the considered point （hereafter referred to as the “true location”）.

The axis of the cylinder shown by the arrow of the indicator line shall be contained within a cylinder of diameter 0.01mm whose axis matches datum axis line A.

If symbol φ is attached before the numerical value that indicates the tolerance, the tolerance range is the range within a cylinder of diameter t whose axis matches the datum axis line.

The center plane shown by the arrow of the indicator line shall be contained between two parallel planes separated by 0.08mm and arranged symmetrically with respect to the datum center plane A.

The tolerance range is the range contained between two parallel planes separated by distance t and arranged symmetrically with respect to the datum center plane.

The radial run-out of the cylinder surface shown by the arrow of the indicator line shall not exceed 0.1mm on any measuring plane normal to the datum axis line when the cylinder is rotated by one rotation about the datum axis line A−B.

The tolerance range is the range contained between two concentric circles separated in the axial direction by distance t and the centers of which are situated on the datum axis line on any measuring plane normal to the datum axis line.

The total radial run-out of the cylinder surface shown by the arrow of the indicator line shall not exceed 0.1mm at any point on the cylinder surface when the cylindrical part is rotated about the datum axis line A−B.

The tolerance range is the range contained between two coaxial cylinders having axes agreeing with the datum axis line and separated from each other by distance t in the radial direction.

■Types and symbols of geometrical tolerances

The meanings of the lines used in the drawings in the “definition of tolerance range” column are as follows.Thick solid or broken line: Shape Thin dash-dot line: Center line Thick dash-dot line: DatumThin alternating long and two short dashes line: Supplementary projection plane or section plane Thin solid or broken line: Tolerance range Thick alternating long and two short dashes line: Projection of shape onto supplementary plane or section plane

If a tolerance frame is connected to a dimension that indicates the diameter of a cylinder, the axis line of the cylinder shall be contained within a cylinder of 0.08mm diameter.

If the symbol φ is attached before the numerical value that indicates the tolerance range, this tolerance range is the range within a cylinder of diameter t.

This surface shall be contained within two parallel planes separated by 0.08mm.

The tolerance range is the area between two parallel planes separated by distance t.

The circumference in any section normal to the axis shall be contained between two concentric circles separated by 0.1mm on the same plane.

The tolerance range in the considered plane is the area between two concentric circles separated by distance t.

The considered surface shall be contained between two coaxial cylinder surfaces separated by 0.1mm.

The tolerance range is the range contained between two coaxial cylinder surfaces separated by distance t.

In any cross-section parallel to the projection plane, the considered profile shall be contained between the two envelope curves formed by a 0.04mm diameter circle, the center of which is situated on the theoretically correct profile curve.

The tolerance range is the range contained between the two envelope curves formed by a circle with diameter t, the center of which is situated on the theoretically correct profile curve.

The considered surface shall be contained between the two enveloping surfaces formed by a 0.02mm diameter sphere, the center of which is situated on the surface containing the theoretically correct profile.

The tolerance range is the range contained between the two enveloping surfaces formed by a sphere with diameter t, the center of which is situated on the theoretically correct profile surface.

The surface shown by the arrow of the indicator line shall be contained between two planes parallel to the datum plane A and separated by 0.01mm in the direction of the arrow of the indicator line.

The tolerance range is the range contained between two planes parallel to the datum plane and separated by distance t.

The axis of the cylinder shown by the arrow of the indicator line shall be contained within a cylinder of diameter 0.01mm that is perpendicular to the datum plane A.

If symbol φ is attached before the numerical value indicating the tolerance range, this tolerance range is the range contained within a cylinder of diameter t that is perpendicular to the datum plane.

The surface shown by the arrow of the indicator line shall be contained between two parallel planes which are inclined with theoretical exactness by 40 degrees to the datum plane A, and which are separated by 0.08mm in the direction of the arrow of the leader line.

The tolerance range is the range contained between two parallel planes inclined at a specified angle to the datum plane and separated from each other by distance t.

The point shown by the indicator line shall be contained within a 0.03mm diameter circle with its center situated at the true location 60mm from datum line A and 100mm from datum line B.

The tolerance range is the range contained within a circle or sphere of diameter t with its center situated at the theoretically exact location of the considered point （hereafter referred to as the “true location”）.

The axis of the cylinder shown by the arrow of the indicator line shall be contained within a cylinder of diameter 0.01mm whose axis matches datum axis line A.

If symbol φ is attached before the numerical value that indicates the tolerance, the tolerance range is the range within a cylinder of diameter t whose axis matches the datum axis line.

The center plane shown by the arrow of the indicator line shall be contained between two parallel planes separated by 0.08mm and arranged symmetrically with respect to the datum center plane A.

The tolerance range is the range contained between two parallel planes separated by distance t and arranged symmetrically with respect to the datum center plane.

The radial run-out of the cylinder surface shown by the arrow of the indicator line shall not exceed 0.1mm on any measuring plane normal to the datum axis line when the cylinder is rotated by one rotation about the datum axis line A−B.

The tolerance range is the range contained between two concentric circles separated in the axial direction by distance t and the centers of which are situated on the datum axis line on any measuring plane normal to the datum axis line.

The total radial run-out of the cylinder surface shown by the arrow of the indicator line shall not exceed 0.1mm at any point on the cylinder surface when the cylindrical part is rotated about the datum axis line A−B.

The tolerance range is the range contained between two coaxial cylinders having axes agreeing with the datum axis line and separated from each other by distance t in the radial direction.

■Axial tightening force and fatigue limit when fastening with bolts

・ When calculating the suitable axial tightening force for bolt tightening, the maximum force shall be 70% of the standard proof strength using the torque control method, and the force shall be within the elastic range.・Bolt fatigue strength under repeated load must not exceed the maximum allowable value.・The bolt and nut seat must not cause any depression in the fastened part.・Tightening must not cause any damage to the fastened part.

■Calculation of axial tightening force and tightening torqueThe relationship of axial tightening force Ff is shown by Formula（1）.Ff＝0.7×σy×As ……（1）Tightening torque TfA is found from Formula（2）.TfA＝0.35k（1＋1/Q）σy・As・d……（2）

■Sample calculationFind the suitable torque and axial force when using an M6 hexagon socket head cap screw（strength class 12.9）to fasten soft steel to soft steel, and tightening with oil lubrication.・�The suitable torque is found by Formula（2）, as shown below.

TfA ＝0.35k（1＋1/Q）σy・As・d ＝0.35・0.17（1＋1/1.4）112・20.1・0.6

＝138［kgf・cm］

k : Torque coefficientd : Bolt nominal diameter［cm］Q : Tightening coefficientσy : Proof strength（112 kgf/mm2 for strength class 12.9）As : Bolt effective cross-section area［mm2］

・�Axial force Ff is found from Formula（1）, as shown below. Ff＝�0.7×σy×As

0.7×112×20.1 1576［kgf］

Methods of bolt tightening include the torque control method, torque gradient control method, rotation angle control method, and extension measurement method. The torque control method is most commonly used, due to its simplicity.

Indicating the strength class Example: 12.9

Proof strength（yield stress）: 90% of minimum tensile strength Minimum tensile strength is 1220 N/mm2 ｛124kgf/mm2｝ 10.9

Proof strength（yield stress）: 90% of minimum tensile strength Minimum tensile strength is 1040 N/mm2｛106kgf/mm2｝

■Bolt strength1）When bolt is subjected to tensile load

Pt ＝σt×As……（1）＝πd2σt/4… （2）

Example: Find a suitable size for a single hexagon socket head cap screw that will be subjected to repeated（pulsating）tensile loads of P＝200 kgf. （Hexagon socket head cap screw material: SCM435, 38～43 HRC, strength class 12.9） From formula（1）:

As ＝Pt/σt ＝200/22.4 ＝8.9［mm2］

Finding the effective cross-section area larger than this value from the table at right shows that a 14.2［mm2］M5 cap screw should be selected. With additional consideration for the fatigue strength, and based on the strength class of 12.9 in the table, we select an M6 screw with maximum allowable load of 213 kgf.

2） For stripper bolts and others which are subjected to tensile impact loads, the selection is made based on the fatigue strength. （The bolt is subjected to 200 kgf loads in the same way. Stripper bolt material: SCM 435 33～38 HRC, strength class 10.9.）

From the table at right, for a strength class of 10.9 and a maximum allowable load of 200 kgf, the suitable bolt is a 318［kgf］M8. Therefore we select a 10 mm MSB10 with a M8 thread section. When the bolt is subjected to shear load, also use a dowel pin.

■Screw plug strength

Find the maximum allowable load P when a MSW30 screw plug is subjected to impact load.（MSW30 material: S45C, tensile strengthσb at 34～43 HRC 65 kgf/mm2）Assuming fracture due to shear occurs at the MSW root diameter location, the maximum allowable load P ＝τt×A.

＝3.9×107.4 ＝4190［kgf］

When the tap is a soft materials, find the maximum allowable shear from the inside thread root diameter.

■Dowel pin strength

Find a suitable size for a single dowel pin which is subjected to repeated（pulsating）shear loads of 800 kgf. （Dowel pin material: SUJ2 hardness 58 HRC or higher）

P＝A ×τ ＝πD2τ/4

D＝√（4P）/（πτ）＝√（4×800）/（3.14×19.2） ≒7.3

For an MS dowel pin, select a size of D8 or larger. In addition, selecting a single size for all dowel pins makes it possible to reduce items such as tools and inventory.

Yield stress for strength class 12.9σb＝112［kgf/mm2］Maximum allowable stressσt＝σb/（safety factor）（From table above, safety factor ＝5）

＝112/5 ＝22.4［kgf/mm2］

Pt : Tensile load in axial direction［kgf］σb : Bolt yield stress［kgf/mm2］σt : Bolt maximum allowable stress［kgf/mm2］（σt＝σb/（safety factorα））

As : Bolt effective cross-section area［mm2］ As＝πd2/4

d : Bolt effective diameter（root diameter）［mm］

The information provided here is only an example of calculating the strength. For actual selections, it is necessary to consider the hole pitch accuracy, hole perpendicularity, surface roughness, true roundness, plate material, parallelism, use of hardening, accuracy of the press machine, product production volume, tool wear, and various other conditions. Therefore the strength calculation value should be used only as a guide. （It is not a guaranteed value.）

Shear cross-section area A＝Root diameter d1×π×L （Root diameter d1≒M－P） A＝（M－P）πL＝（30－1.5）π×12 ＝1074［mm2］Yield stress≒0.9×Tensile strengthσb＝0.9×65＝58.2Shear stress ≒0.8×Yield stress

＝46.6Maximum allowable shear stressτt ＝Shear stress / （Safety factor 12）

＝46.6/12＝3.9［kgf/mm2］

① Select the θ column on the left side of the conversion chart and find the deg （angle°）.

② After verifying the type of trigonometrical function listed at the top of the conversion chart, determine the value of the target deg （angle°）.

If the deg （angle°） includes figures after the decimal point, covert to a value of degrees （°） and minutes （'）. Ex.: 5.5° becomes 5°30' （5 degrees, 30 minutes）. （1 degree＝60 minutes）
