3/8-24 x 2 1/2 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. 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 torque-once joints where a locking pellet is not required, plain 18-8 Socket Head Cap Screws may be the simpler routing. Need the pellet in a non-catalog size or position? In-house pelletizing gives Cold Headers a practical route for special requests.
