Value Collection 86853348 Hex Head Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 86853348 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, structural, and equipment assembly work. Manufactured from Grade 8 steel with a zinc-plated finish, this screw delivers the tensile strength required for demanding load-bearing connections. The 5/16-18 UNC thread pattern and 1-1/4 inch length under head make it a standard choice for through-bolted joints and tapped-hole installations across a wide range of trade applications. Machinists, millwrights, HVAC installers, and general tradespeople rely on Grade 8 hardware where strength and corrosion resistance are both required.

This fastener is suited for use in residential and light commercial equipment assembly, structural bracketing, and mechanical component mounting. The zinc plating provides baseline corrosion protection for indoor and sheltered outdoor environments. The fully threaded shank maximizes thread engagement in shallow-tapped holes or thin material stacks. Sold in packages of 10, this screw is appropriate for production assembly, service kits, and field repair work where consistent hardware grade is essential.

Compatibility

Designed as a standard UNC Grade 8 hex head cap screw for use in any application requiring 5/16-18 threaded fasteners with a 1-1/4 inch grip length.

Installation Notes

Install using a standard hex wrench or socket driver sized for a 5/16-18 fastener. Ensure tapped holes or mating nuts are clean and free of debris before installation. Apply thread lubricant or thread-locking compound as required by the application specification. De-energize and isolate any equipment being serviced before fastener removal or replacement.
