This 7/16-20 x 1 1/4 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.
The 7/16-20 x 1 1/4 size is often reviewed for tooling, inspection fixtures, and precision assemblies when the bill of materials calls for an alloy steel cap screw with a nylon insert. Engineers should confirm that the selected size, nylon insert position, and mating threads suit the assembly before substituting from a standard socket cap screw.
Cold Headers supports distributors, OEM sourcing teams, and maintenance operations that need uncommon lengths or exact 1960 Series socket screw sizes.
