This 5/16-24 x 5/8 Alloy Steel Socket Head Cap Screw with Nylon Insert belongs to the Cold Headers 1960 Series for socket head cap screws with prevailing-torque nylon inserts. The insert adds prevailing-torque resistance through localized nylon contact, so the fastener can be considered where service conditions call for added loosening resistance.

Common uses include tooling, inspection fixtures, and precision assemblies, where a precise socket head fastener with added loosening resistance can simplify maintenance and replacement planning. Selection should account for joint geometry, thread engagement, installation access, and whether a nylon insert is appropriate for the service environment.

Cold Headers supports distributors, OEM sourcing teams, and maintenance operations that need uncommon lengths or exact 1960 Series socket screw sizes.
