5/16-24 x 2 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. The insert is positioned in the threaded body so the screw can develop prevailing torque during engagement.

Typical applications include pharmaceutical fixtures, inspection stations, and clean industrial work cells, 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 torque-once joints where a locking pellet is not required, plain 18-8 Socket Head Cap Screws may be the simpler routing. For non-catalog pellet positions or unusual sizes, in-house pelletizing at the Chicago facility gives Cold Headers added sourcing flexibility.
