Value Collection 97151 Hex Head Cap Screw 5/8-11 X 2.5 in Grade 5

Product Description

The VALUE COLLECTION 97151 is a partially threaded hex head cap screw designed for general industrial and mechanical fastening applications. Manufactured from Grade 5 steel with no surface coating applied, this fastener measures 5/8-11 thread size with a 2.5-inch length under the head. The coarse UNC thread form provides strong mechanical engagement in standard tapped holes and nuts. It conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for structural assemblies, equipment mounting, and maintenance repairs across a wide range of trade and industrial settings.

This hex head cap screw is suited for use in mechanical, HVAC, plumbing, and general construction applications where a standard inch-series Grade 5 fastener is required. The partial thread configuration is typical for longer-length cap screws, allowing a smooth shank to pass through clearance holes before engaging the threaded section. Each package contains 25 pieces, making it practical for service technicians and tradespeople who need a ready supply on hand. It is installed using standard hex wrenches or socket drive tools.
