Value Collection 99029 5/16-18 X 1 in Grade 8 Hex Cap Screw 100pk

Product Description

The VALUE COLLECTION 99029 is a Grade 8 hex head cap screw in a 5/16-18 UNC thread size with a 1-inch length under head. Fully threaded along its entire shank, this fastener is manufactured from steel with a bright, uncoated finish. Grade 8 classification indicates high tensile strength, making these screws suitable for demanding mechanical and structural applications. This listing is sold as a pack of 100. Installation is performed by mechanics, millwrights, maintenance technicians, and trade professionals working in light industrial, HVAC equipment assembly, plumbing fixture mounting, and general mechanical service environments.

These cap screws are intended for use in bolted assemblies where a high-strength inch-series fastener is required. The 5/16-18 UNC thread pattern is a standard coarse-thread configuration widely used across mechanical equipment, framing brackets, structural connections, and trade equipment mounting applications. The fully threaded shank provides maximum thread engagement across the full 1-inch grip length, which is particularly useful in thinner material stacks and close-tolerance fastening situations.
