1/2-13 x 3 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. Nylon contact at the thread adds frictional resistance while preserving the standard internal hex drive arrangement.

This size is often reviewed for beverage filling equipment, changeover tooling, and stainless guide assemblies when a stainless cap screw must retain a familiar socket head form. 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. Since 1962, Cold Headers has helped buyers locate specialty socket fasteners for production, repair, and distributor requirements.
