Value Collection 872359PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 872359PR is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. It features a 1/2-13 UNC thread and measures 1-1/2 inches under the head with full threading along the shank. The 3/8-inch drive hex socket allows installation with standard Allen keys or hex bit drivers. Constructed from alloy steel with a zinc-plated finish, this screw delivers solid mechanical strength with basic corrosion resistance. It meets ASME B18.8 and ASTM A574 standards. Machinists, millwrights, and maintenance mechanics are the typical installers.

This screw is suited for general mechanical assembly, machine frames, fixtures, tooling plates, and equipment maintenance applications where a recessed-drive cap screw is required. The fully threaded shank provides consistent thread engagement across the full grip length, making it a practical choice in through-hole and threaded-insert applications. Minimum order quantity is 10 pieces, and the package quantity is 1 unit per package.
