1/4-28 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. 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 torque-once joints where a locking pellet is not required, plain 18-8 Socket Head Cap Screws may be the simpler routing. Cold Headers installs nylon inserts in-house for supported socket-cap configurations, with odd-size sourcing handled through the quote process.
