Value Collection 581350PR Hex Socket Cap Screw 12-28 Unf

Product Description

The VALUE COLLECTION 581350PR is a fully threaded hex socket cap screw designed for precision fastening in mechanical, industrial, and trade applications. Sized at 12-28 UNF with a 5/8 inch length under the head, this screw uses a 5/32 inch hex drive and is manufactured from alloy steel with a black oxide finish for corrosion resistance. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for high-stress fastening tasks. The black oxide coating reduces light reflection and provides a baseline level of surface protection in controlled environments. This screw is appropriate for HVAC, electrical, plumbing, and general mechanical assembly work where a compact, high-strength fastener is required.

This fastener is suited for use in residential and light commercial mechanical assemblies, panel fabrication, equipment mounting, and component installation. Its fine 12-28 UNF thread pitch provides strong thread engagement in thin materials or close-tolerance applications. The fully threaded shank allows for maximum grip along the entire usable length. Technicians working on equipment access panels, motor mounts, control enclosures, and similar assemblies will find this size practical for standard hex key tooling.
