Value Collection A996216 Hex Head Cap Screw 5/16-18 X 2 in Grade 8

Product Description

The VALUE COLLECTION A996216 is a Grade 8 alloy steel hex head cap screw sized 5/16-18 UNC x 2 inches under the head. Grade 8 is the highest commonly stocked SAE bolt grade, offering tensile strength suitable for demanding structural and mechanical fastening applications. The zinc-plated finish provides a base level of corrosion resistance for general indoor and light outdoor use. These fasteners are installed by electricians, HVAC technicians, plumbers, equipment fabricators, and maintenance professionals working in both residential and commercial trade environments. Each pack contains 25 screws, driven with a standard 1/2-inch hex head socket or wrench.

This screw is suited for medium-duty bolted connections where a coarse UNC thread profile is specified. The 5/16-18 thread designation indicates a 5/16-inch nominal diameter with 18 threads per inch on the Unified National Coarse standard. Common applications include equipment mounting, bracket fabrication, panel attachment, and mechanical assembly in HVAC, plumbing, and electrical trade work. The 2-inch under-head length accommodates moderate material stack-ups with or without standard hardware such as washers and nuts.

Key Features

• Grade 8 alloy steel construction for high tensile strength in structural fastening

Installation Notes

Installation is performed by licensed tradespeople or qualified maintenance personnel using a 1/2-inch socket, ratchet, or combination wrench. Always de-energize and lock out electrical equipment and isolate mechanical systems before fastening into or near live components. Follow applicable codes and equipment manufacturer torque guidelines for the specific joint material and bolt grade. Do not substitute a lower-grade fastener in a location specified for Grade 8 without engineering review.
