Value Collection 99062 Hex Cap Screw 3/8-16 X 3 in Grade 8 50pk

Product Description

The VALUE COLLECTION 99062 is a 3/8-16 hex head cap screw rated to Grade 8 steel, designed for high-strength fastening applications in mechanical, industrial, and trade assembly work. Measuring 3 inches under the head with a partially threaded shank, this fastener meets ASME B18.2.1 dimensional standards. The Unified National Coarse (UNC) thread form provides reliable engagement in tapped holes and standard nuts. The bright, uncoated finish leaves the base steel exposed, which is common in dry or controlled environments where additional corrosion protection is not required. Sold in a package quantity of 50, this SKU suits installers and technicians who need a reliable supply on hand for recurring fastening tasks.

This cap screw is suited for structural and mechanical assembly applications where a high-strength fastener is specified. Grade 8 hardware is commonly called out in equipment mounting, bracket installation, compressor and blower assembly, and general mechanical fabrication in HVAC, plumbing, and industrial service environments. The partially threaded shank provides a smooth bearing surface in applications where the fastener passes through a clearance hole before engaging a tapped surface or nut. These screws are appropriate for use by licensed technicians, millwrights, and experienced trade professionals.

Installation Notes

Installation is performed by mechanics, HVAC technicians, plumbers, or other licensed trade professionals using standard 9/16-inch hex sockets or open-end wrenches. Always de-energize equipment and relieve system pressure before disassembling or reassembling fastened assemblies. Grade 8 fasteners should not be substituted with lower-grade hardware when a Grade 8 specification is called out by the equipment manufacturer. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for the assembly being serviced.
