Value Collection 201208PR Button Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 201208PR is a button socket cap screw designed for fastening applications that require a low-profile head and reliable clamping strength. Manufactured from alloy steel with a black oxide finish, this screw resists corrosion and reduces light reflection in service environments. The 1/2-13 UNC thread pattern and 3A thread fit class deliver tight tolerances and consistent engagement. With a hardness rating of 36-43 HRC and compliance with ANSI/ASME B18.3 and ASTM F835, this fastener meets recognized industry standards for mechanical fasteners used in structural and equipment assembly work.

This button socket cap screw is suited for machine assembly, jig and fixture building, tooling plates, and general industrial fastening where a flush or near-flush head profile is needed. The 5/16-inch hex socket drive is compatible with standard hex keys and socket drivers. It is commonly installed by machinists, maintenance mechanics, and millwrights in manufacturing, fabrication, and equipment service environments.
