This 6-40 x 1 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 prevailing-torque insert is useful when a drawing specifies a socket head cap screw with a nylon locking element rather than a standard socket screw.
Common uses include driven equipment, actuator mounts, and controlled motion 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 provides catalog depth for specialty socket fasteners and helps purchasers identify the correct alloy steel nylon insert configuration.
