1/4-28 x 7/8 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert is built for drawings that call for both stainless material and prevailing-torque thread locking. Its locking element supports service where a standard all-metal cap screw may need an added thread-locking feature.

Use it for wash-bay equipment, maintenance fixtures, or replacement assemblies after confirming thread engagement, drive access, and the mating material. 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 can help confirm the exact-size 1960 Series stainless nylon-insert part before quoting availability.
