Value Collection R82222334 Hex Head Cap Screw 1/2-20

Product Description

The VALUE COLLECTION R82222334 is a 1/2-20 hex head cap screw with a 1-1/2 inch length under head, manufactured from 18-8 stainless steel with an uncoated finish. The 1/2-20 thread designation indicates a half-inch nominal diameter with 20 threads per inch on a Unified National Fine (UNF) thread form. 18-8 stainless steel provides solid corrosion resistance suitable for general industrial, mechanical, and structural fastening applications. This screw is sold as a single piece and is appropriate for use by maintenance technicians, mechanical contractors, and trade professionals who require a mil-spec-compliant fastener in stainless steel.

This fastener is used across a wide range of industrial and mechanical assemblies where a UNF thread and corrosion-resistant material are required. The uncoated 18-8 stainless steel construction makes it suitable for environments with moderate moisture exposure. It meets multiple military standard specifications, making it appropriate for aerospace, defense, and industrial maintenance applications where documented standards compliance is required.

Installation Notes

This fastener should be installed by a qualified mechanic or maintenance technician using a standard hex wrench or socket sized for a 1/2-inch hex head cap screw. Apply appropriate torque per the assembly specification or engineering drawing for the application — do not exceed the published torque limit for 18-8 stainless steel of this thread size. Stainless steel fasteners are susceptible to galling during installation; use an anti-seize compound where required by the application. Always confirm thread engagement depth and mating material compatibility before final installation.
