1/2-13 x 2 1/2 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. 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. 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.
