1/4-28 x 1 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert gives machine builders a corrosion-resistant socket cap screw with an integral nylon insert. The pellet presses against the mating thread to provide prevailing torque without changing the socket head geometry.
Typical applications include instrumentation panels, sensor brackets, and compact machine frames, where the exact thread and length help match drawings, service records, and replacement needs. The nylon element gives the joint a locking feature, but it also limits service temperature compared with an all-metal socket screw.
For torque-once joints where a locking pellet is not required, plain 18-8 Socket Head Cap Screws may be the simpler routing. Cold Headers has supplied specialty socket fasteners since 1962 and helps source exact stainless sizes and uncommon lengths. The 1960 Series name identifies the modern ASME B18.3 head-proportion standard for socket head cap screws, successor to the older 1936 series, not a year of manufacture.
