YDTech® MANUFACTURER of cylindrical locating^dowel pins steel(A,B,C,D types); supplier of internal thread cylindrical dowel pins(parallel pins) in china.

type A, B, C & D are recommended for un hardened and

are made from C-40 (EN-8) material. Type E is for

hardened from silver steel material.

internal threaded cylindrical (dowel) pin soft are for easy extraction from blind holes.

they are manufactured in soft condition from C40material. internal threaded

cylindrical (dowel) pin hard are manufactured from case hardened alloy steel or as

per buyer requirement. airvent is provided for easy entry.

regarding size and precision, we manufactures precision

dowel pins to exacting tolerances. We can produce

dowel pins to a tolerance of +/-0.0002 utilizing stainless

steel, tool steel, brass, or aluminum.

the dowel pins are ground cylindrical pins primarily

manufactured for precise locating devices in machinery and assemblies. Steel dowel pins are machined to tight

tolerances with the DIN and ISO standard pins being m6 on the diameter. the corresponding holes are usually

reamed to allow for a press fit, clearance fit or transition fit.

we carefully consider the dowel pins material to be used

as well as the dowel destination. We take into account

the ductility of the destination hole and the ductility of

the dowel pins material being used to manufacture the

machined parts with accurate dimensions.
