5/16-18 x 2 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. Its locking element supports service where a standard all-metal cap screw may need an added thread-locking feature.
This size is often reviewed for pump skids, utility frames, and serviceable covers 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.
