The VALUE COLLECTION R63038488 is a hex head cap screw designed for fastening applications requiring corrosion resistance and dimensional precision. Built to Unified Fine Thread (UNF) standards, this fastener features a 5/16-24 thread size with a 1-1/4 inch length under head and is manufactured from 18-8 stainless steel. The 1/2 inch hex drive head accepts standard hex wrenches and sockets. The 18-8 stainless alloy provides solid resistance to oxidation and many common chemicals, making it a dependable choice in environments where carbon steel fasteners would corrode prematurely. Licensed tradespeople and maintenance technicians across mechanical, plumbing, and electrical trades rely on this grade of fastener for structural and equipment assembly work.
This screw is suited for light to medium-duty fastening tasks in residential and commercial maintenance, equipment assembly, and mechanical system installations. The UNF thread form provides finer thread engagement than coarse thread equivalents, which is beneficial in applications requiring greater holding strength in thinner material or where vibration resistance is a priority. Typical uses include panel mounting, equipment bracketing, and general mechanical assembly where stainless steel is specified.
Designed as a standard-dimension UNF hex head cap screw for use in any application calling for a 5/16-24 x 1-1/4 inch stainless steel fastener.
Installation is performed by hand-starting the screw into a pre-tapped or through-hole before final tightening with a hex wrench or socket. Power down or de-energize any equipment before fastening components near live electrical parts. Avoid cross-threading by confirming thread engagement by hand before applying torque. Follow applicable mechanical codes and equipment manufacturer specifications for fastener seating and assembly procedures.
