Value Collection 201202PR Button Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 201202PR is a button socket cap screw designed for use in mechanical assemblies where a low-profile fastener head is required. The screw features a 1/2-13 UNC thread in a 1-inch length under head, fully threaded, with a 5/16-inch hex socket drive. It is manufactured from alloy steel and finished with black oxide coating to provide a degree of corrosion resistance in indoor mechanical environments. Hardness is rated at 36-43 HRC, meeting ANSI/ASME B18.3 and ASTM F835 standards. Machinists, millwrights, and mechanical contractors install this type of fastener where a flush or recessed head profile is needed.

This button socket cap screw is suited for general mechanical and industrial applications including machine frames, fixtures, guards, and equipment enclosures. The black oxide finish makes it a common choice for applications requiring a uniform dark appearance alongside corrosion resistance above that of plain steel. The fully threaded shank ensures engagement along the full length in through-hole and thin-material installations. A minimum order quantity of 100 pieces applies.

Compatibility

Designed as a standard UNC button socket cap screw suitable for general industrial and mechanical assembly applications requiring a 1/2-13 thread and a low-profile button head.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical technicians using a 5/16-inch hex key or socket bit. Ensure the mating thread is clean and free of debris before installation. De-energize and lock out any equipment before fastener service on live machinery per applicable safety procedures. Do not substitute this fastener in structural or safety-critical load paths without verifying the required thread fit class and grade for the application.
