1/4-20 x 3/8 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert serves equipment that needs top-side socket access and a built-in prevailing-torque feature. 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. Slight magnetism from cold working can be normal for 18-8 stainless, so selection should reflect the actual assembly environment and mating hardware.
For rounded exposed heads with the same locking concept, review 18-8 Button Head Socket Cap Screws with Nylon Insert. Cold Headers has supplied specialty socket fasteners since 1962 and helps source exact stainless sizes and uncommon lengths.
