6-40 x 1 3/4 1960 Series Alloy Steel Socket Head Cap Screw with Nylon Insert combines alloy steel construction, an internal hex drive, and a nylon locking insert in one cataloged fastener. 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 industrial equipment, material-handling systems, and machine frames, where a precise socket head fastener with added loosening resistance can simplify maintenance and replacement planning. For replacement work, matching the thread, length, pellet diameter, and pellet location helps align the part with service records and existing hardware.

Cold Headers has supplied specialty socket fasteners since 1962 and supports exact-size sourcing for difficult-to-find socket products.
