1/4-20 x 1 3/4 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert combines the familiar socket head profile with a nylon insert for added loosening resistance. The pellet presses against the mating thread to provide prevailing torque without changing the socket head geometry.

Typical applications include washdown conveyors, stainless equipment frames, and guarded production machinery, where the exact thread and length help match drawings, service records, and replacement needs. 18-8 stainless is a practical choice for ordinary moisture exposure, washdown-adjacent machinery, and equipment where a clean stainless finish is specified.

For countersunk installations, 18-8 Flat Head Socket Cap Screws with Nylon Insert keep the locking feature in a different head style. For non-catalog pellet positions or unusual sizes, in-house pelletizing at the Chicago facility gives Cold Headers added sourcing flexibility.
