Value Collection 451124BR Hex Head Cap Screw 5/8-11 X 8 in Grade 8

Product Description

The VALUE COLLECTION 451124BR is a Grade 8 hex head cap screw in a 5/8-11 UNC thread size with an 8-inch length under the head. Manufactured from steel with a bright, uncoated finish, this fastener is partially threaded and conforms to ASME B18.2.1 dimensional standards. Grade 8 steel provides high tensile strength, making it suitable for demanding structural and mechanical assembly applications. The hex drive accepts a 5/16-inch hex key for installation. This screw is a standard inch-measurement fastener used by maintenance professionals, millwrights, and general contractors across a wide range of industrial and construction settings.

This cap screw is suited for use in bolted assemblies where high-strength fasteners are required, including equipment mounting, structural steel connections, and heavy machinery fabrication. The partial thread design is appropriate for applications requiring a grip length, such as fastening through thick material where a fully threaded screw would not seat properly against the bearing surface. It is sold and packaged individually.
