Description

Stainless Steels are broadly defined as Iron alloys containing from 12 to 30% Chromium and from 0 to 20% Nickel. This analysis is further modified by additions of Carbon and other minor elements which contribute specific effects either to control mechanical properties or to improve corrosion resistance. The corrosion resistance of Stainless Steels is attributed to a surface phenomenon, passivity. When oxygen comes in contact with the surface it forms an invisible film which protects the underlying metal from rusting and corrosion under severe environment.

characteristics

The family of Stainless Steels is divided into three general classifications:“Austenitic” Stainless Steels make up the general group of the 18-8 (or 300) series. They are the Chromium-Nickel type containing upwards of 8% Nickel. They are not hardenable by heat treatment, non-magnetic for practical purposes and offer the greatest degree of corrosion resistance.”Martensitic” Stainless Steels contain from 12 to 20% Chromium. They are magnetic and hardenable. Type 410 and 416, common fastening alloys, are Martensitic Stainless Steels.“Ferritic” alloys are also Chromium Stainless Steel alloys. They are magnetic and not hardenable by heat treatment. Type 430 is an example.

Uses

There are almost as many uses for Stainless Steel fastenings as there are problems of corrosion, temperature and strength. Because of its high tensile strength, corrosion resistant qualities and ability to attain a mirror-like finish it is one of the most versatile of all metals. Applications include its use in the petroleum, chemical, food, plumbing, transportation and oil equipment industries to mention just a few. Listed on page 139 are the types of various Stainless Steel alloys which are most frequently used in the manufacture of fastenings.

inDUstry stanDarDsMost industrial fasteners are covered by two basic standards: one for materials and properties; the other, for dimensions and tolerances. Specifications for materials and properties are published by the American Society for Testing and Materials (ASTM), although other groups such as the Society of Automotive Engineers (SAE) also publish specifications covering these requirements.

Standards for dimensions and tolerances are issued by the American National Standards Institute (ANSI) in cooperation with the American Society of Mechanical Engineers (ASME) and the Industrial Fasteners Institute (IFI).

Where applicable, published specifications covering a particular fastener will be referenced in the section of this booklet dealing with that fastener.

When referring to standards and specifications, we will use only the well-known initials of the above societies-ANSI, ASME, IFI, ASTM and SAE.

Standard fasteners are basic industrial fasteners - square and hex bolts, cap screws, carriage bolts, plow bolts, lag screws, studs, nuts, rivets and others - which have been standardized over the years as to type‘, style, usage, properties, dimensions and tolerances.

These include a vast range of sizes and types stocked by distributors and manufacturers for an almost limitless range of applications: the assembly and maintenance of vehicles, appliances, farm equipment, construction equipment, industrial and plant machinery of all kinds, furniture and toys.

Wherever there’s a need for holding parts together, holding them apart, holding them up, or holding them down, a standard fastener can usually be found to do the job efficiently and economically.

Modern industrial fasteners are manufactured to a variety of standards covering dimensions, tolerances, materials, mechanical properties, testing procedures, etc.

Basic Fastener types

A Bolt is a device with a head on one end of a shank or body and a thread on the other end. Designed for insertion through holes in assembly parts, it is mated with a tapped nut. Tension is normally induced in the bolt to compress the assembly by rotating the nut. This may also be done by rotation of the bolt head.

A Screw is a headed and threaded bolt used without a nut. It is inserted into an internally tapped hole and tension is induced by rotation of the screw head.

A stud is a fastener with no head but it has threads at both ends of the shank. It, like a screw, has one end that screws into a tapped hole. A nut is used on the other end to create tension.

If a stud is threaded its entire shank length and a nut used on both ends to create tension, it serves the function of a bolt and is then classified as a Stud Bolt.

Many variations of thesebasic fastener types are available.

terMinoLoGy & MeasUreMents

The diameter of all bolts is measured as the outside of major diameter of the thread. The length of a headed bolt is measured from the largest diameter of the bearing surface of the head to the extreme end of the point in a line parallel to the axis of the bolt. For example, square or hex head bolts are measured from under the head to the end of the bolt; a bolt with a countersunk head is measured overall. The point of a bolt is always included in the measured length.

Headless fasteners such as studs are measured overall, including points, except for continuous-thread alloy studs made to ASTM Specification A193. This type is measured from first thread to first thread.

Bolts have various styles of heads. Some of the more popular styles are illustrated above.

styLes oF heaD

heaVy heaDs anD nUtsBolt users may require a bolt head or nut of greater width to compensate for wide clearance in bolt holes or unusually heavy loading. For such needs we offer heavy bolt heads or nut sizes. Heavy nuts are quite common and readily available in various types and sizes but heavy head bolts have more limited availability.

BoLt anD nUt BearinG sUrFacesCold-upset bolts made on a “boltmaker” usually are washer faced but large or very long bolts may have a flat face (not machined). Nuts made on cold “nut-formers” may have double chamfered or washer faces. Large size nuts have hot-forged washer bearing faces, not machined, unless specially ordered.

Heat treatment covers various techniques that may be used to develop certain end-product characteristics. Customary procedures for fasteners include annealing, stress relieving, case hardening, direct quench and temper, and carbon restoration.

anneaLinG: A thermal cycle involving heating to, and holding at a suitable temperature and then cooling at a suitable rate, for such purposes as reducing hardness, improving machinability, facilitating cold working, producing a desired microstructure, or obtaining desired mechanical or other properties.

stress reLieVinG: A thermal cycle involving heating to a suitable temperature, usually 1000/1200°F, holding long enough to reduce residual stresses from either cold deformation or thermal treatment, and then cooling slowly enough to minimize the development of new residual stresses.

case harDeninG: A term descriptive of one or more processes of hardening steel in which the outer portion, or case, is made substantially harder than the inner portion, or core. Most of the processes involve either enriching the surface layer with carbon and/or nitrogen, usually followed by quenching and tempering, or the selective hardening of the surface layer by means of flame or induction hardening.

QUenchinG anD teMperinG: A thermal process used to increase the hardness and strength of steel. It consists of austenitizing, then cooling at a rate sufficient to achieve partial or complete transformation to martensite. Tempering should follow immediately, and involves reheating to a temperature below the transformation range and then cooling at any rate desired. Tempering improves ductility and toughness, but reduces the quenched hardness by an amount determined by the tempering temperature used.

Standard industrial fasteners are manufactured from either carbon or alloy steels. When strength requirements are moderate, low-carbon steel is used. High-strength fasteners are made from medium-high carbon or alloy steels and are heat treated to develop desired properties. Most fasteners are covered by specifications that define required mechanical properties such as tensile strength, yield strength, proof load, and hardness.

tensiLe strenGth: The maximum tensile stress in pounds per sq. in. which a material is capable of sustaining, as developed by a tension test.

yieLD strenGth: The stress at which a material exhibits a specified deviation from the proportionality of stress to strain. The deviation is expressed in terms of strain, and in the offset method, usually a strain of 0.2 percent is specified.

prooF LoaD: The point to which a material may be stressed without evidence of permanent deformation.

harDness: The resistance of a material to plastic deformation. Usually measured in steels by the Brinell, Rockwell, or Vickers indentation-hardness text methods.

threaD ForMs: Screw threads are spiral grooves produced on the outside of a bolt (external threads) or machined inside a nut (internal threads). Four thread forms have been established by the ANSI: UN (internal and external threads). UNR (external threads only), UNK (external threads only), UNJ (internal and external threads).

cUt Vs. roLL threaDs: The terms “rolled thread” and “cut thread” refer solely to the physical characteristics of commercial bolts or studs, not to the method of thread production. A cut-thread bolt has a shank diameter equal to the threaded diameter; a rolled-thread bolt has a shank diameter less than the threaded diameter.

cLasses oF threaD Fit: Classes of thread fit are distinguished from each other by the amounts of tolerance specified. Classes 1A, 2A, and 3A apply to external threads; Classes 1B, 2B and 3B, to internal threads. Classes 1A and 1B are shown in ANSI standards but are rarely used. Most standard fasteners are produced with a Class 2A fit for bolts and a Class 2B fit for nuts. The Class 2A allowance assures easier assembly of mating parts, minimizes galling and seizing in high-cycle wrench assembly, and can be used to accommodate commercial electroplated finishes. Classes 3A and 3B afford no allowance or clearance for mating parts and are used chiefly for applications where a close tolerance fit is important. Class 5 is a special interference fit which results in an actual overlap of dimensions when threaded parts are fitted together. It is normally used only on the tap-end of studs.

Threading requirements are designated (1) by the number of threads per inch applied to a specific diameter; (2) by the initial letters of the thread standard (UNR or UN); (3) by the letters C, F, or numeral 8 to indicate coarse-, fine-, or 8-thread series; and (4) by the thread fit. The following example illustrates the method of designating a screw thread:

1/2 in. -13 UNRC-2A where

1/2 in. = nominal diameter of thread 13 = number of threads per inch UNR = thread form standard (Unified National Radius-Root) C = coarse-thread series 2A = class of thread fit

The coarse-thread series (UNRC or UNC) is used on the vast majority of bolts and nuts.Number of threads per inch ranges from 20 threads for a 1/4-in.- diameter bolt to 4 threads for a 4-in.-diameter bolt. The fine-thread series (UNRF or UNF) is found mostly in automotive and aeronautical work. Threads per inch range from 28 threads for a 1/4-in.-diameter bolt to 12 threads for a 1-1/2-in.-diameter bolt. There is no fine-thread standard for fasteners over 1-1/2 in.

The 8-thread series (8UNR or 8UN) is used only for sizes over 1 in. in diameter, usually in high-temperature, high pressure service.

SEE NOTESEE NOTE

Bolts - hex and heavy hex

hex bolts are available in two dimensional standards:

• The heavy hex bolt has a head dimension averaging approximately 1/8“ wider across the flats than the standard hex bolt.It is generally used for applications where maximum bearing area is required.

• Hex bolts are offered with UNRC-2A threads in diameters ranging from 1/4” through 2”. Heavy hex bolts with UNRC-2A threads are offered in diameters of 1/2” to 1-1/2” inclusive.

Hex bolts of heat treated carbon or alloy steel are available from cap-screw stock.

SPECIAL NOTE: Hex bolts in a size range from 1/4” thru 3/4” in diameter and in lengths 8” and shorter are often shipped from Cap-screw stock at the Hex bolt price.

However, when ordered as hex bolts there is no guarantee that they will meet all Cap-screw requirements.

types of studs

continUoUs threaD stUDs: Continuous-thread studs are threaded from end to end and are often used for flange bolting with two nuts applied.

Type 1 — General purpose. The length of this type is measured from end to end. Threads are UNRC-2A.

Type 2 — Studs for temperature-pressure piping. These studs are made to the dimensional standard requirements of ANSI B16.5 and have a length measurement requirement different from all other studs, i.e., the length is measured from firstthread to first thread, exclusive of points. Points are flat and chamfered. Threads are UNRC-2A for all sizes 1 in. and under and 8UNR-2A for all sizes

over 1 in.

tap-enD stUDs: Tap-end studs have a short thread on one end, called the tap end which is threaded to a Class NC5 or Class UNRC-3A fit. This end is for screwing into a tapped hole. The other or nut end is threaded with a Class UNRC-2A fit. Length of the stud is measured overall. The tap end has a chamfered point, but the nut end may have either a chamfered or round point, at the manufacturer’s option. Tap-end studs are available in four types, as follows:

Type 1 — Unfinished, have a full diameter but no standard body tolerances.Type 2 — Finished, having either an undersize body with rolled threads or a full-size body with cut threads, at the manufacturer’s

option. The body portion will be finished to a minimum Class 2A pitch diameter or maximum basic major diameter of the nut-end thread.

Type 3 — Finished full-body, having tolerances equal to that on major diameter of Class 2A threads.Type 4 — Finished close-body, milled or ground to tolerances specified by the user.

DoUBLe-enD stUDs: Double-end studs have equal-length threads on each end to accommodate a nut and are threaded to a Class 2A fit. Length of stud is measured overall. Both ends have chamfered points, but round points may be furnished on either or both ends at the manufacturer’s option. This style is furnished in the same four types listed for tap-end studs. Double-end studs are used for flange bolting or other applications where torquing from both ends is necessary or desirable.

Most steel grades not heat treated or quenched and tempered can be furnished on special order for production quantities. Only the Type 2 continuous thread studs made to specification ASTM A193 grade B7 are stocked in a full range of sizes. Page 155 lists all the commonly available grades of Alloy steel quenched and tempered studs.

Tap end and double end studs are not available from stock - They are available only on special order.

Commonly used are the following grades of heat-treated alloy steel for high-pressure or extreme temperature service in diameters of 1/2 in. to 2 in., inclusive. Other grades and other diameters are available on special order.

astM a354 - Grades Bc and BDHeat treated alloy steels for applications at normal atmospheric temperatures where high strength is required.

astM a193 - Grade B7A heat treated chromium-molybdenum steel widely used for medium high-temperature service.

astM a193 - Grade B16A heat treated chromium-molybdenum-vanadium steel widely used for high-temperature service.

astM a320 - Grade L7This grade is intended for low-temperature service down to minus 150° F and has a minimum Charpy impact value

of 15 ft-lb at this temperature. Sizes 2-1/2 in. and under.

astM a320 - Grade L43The same properties offered by Grade L7 in sizes up to 2-1/2 in. are obtainable up to 4 in. in Grade L43.

Heat-treated alloy steel bolts and threaded bars are also available in the grades listed above - bolts in diameters of 3/8 in. to 1-1/4 in., inclusive; bars in diameters of 1/2 in. to 2 in., inclusive. These are available only on special order.

CONCRETE ACCESSORIES

THREADED ACCESSORIES

COIL THREAD

CONCRETE STAKES

Coil Thread Rod is manufactured using high tensile steel and incorporates an easy-flow thread to provide for ease of installation.

Coil Thread Rod is available in 12 ft lengths

Watson Metal will provide the product cut to length at a modest

increase in price. Watson Coil Thread is manufactured in America

from Steel produced in America. We meet all requirements of any

state D.O.T. Imported Hex Nuts are available for all diameters.

Concrete Stakes are used to secure wood or metal forms to the ground. For concrete placement, they can be removed and re-used many times. Manufactured from 1040 steel to withstand the hammer blows, the stakes have numerous nail holes to insure one will line up with the form. The nominal ¾ round stake (0.718” diameter) meets the IFI Specifications and has a paint finish to prolong the life before rust. The stakes are packed in units of ten with plasticated capes, wrapped and palletized by length.

We can offer a nominal 7/8” diameter round stake and a 3/8” thick flat stake. In addition, if demand warrants, we will add a full ¾” diameter. These stakes, imported from India, are very versatile and can be used in a myriad of projects outside of concrete forming.
