5/16-18 x 3/4 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert pairs stainless construction with a nylon locking pellet for joints exposed to moisture and vibration. 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.

Use the exact thread, length, pellet diameter, and pellet location when matching drawings or service records. Cold Headers has supplied specialty socket fasteners since 1962 and helps source exact stainless sizes and uncommon lengths.
