This 4-40 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 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.
In driven equipment, actuator mounts, and controlled motion assemblies, the internal hex drive allows compact tool access while the alloy steel body keeps the product aligned with drawings that specify this material. For replacement work, matching the thread, length, pellet diameter, and pellet location helps align the part with service records and existing hardware.
Cold Headers supports distributors, OEM sourcing teams, and maintenance operations that need uncommon lengths or exact 1960 Series socket screw sizes.
