5/16-24 x 7/8 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert is selected when stainless hardware and thread-friction locking are needed in the same fastener. Its locking element supports service where a standard all-metal cap screw may need an added thread-locking feature.

Use it for material-handling systems, equipment guards, or panel-mounted hardware after confirming thread engagement, drive access, and the mating material. 18-8 stainless is a practical choice for ordinary moisture exposure, washdown-adjacent machinery, and equipment where a clean stainless finish is specified.

For countersunk installations, 18-8 Flat Head Socket Cap Screws with Nylon Insert keep the locking feature in a different head style. Cold Headers can help confirm the exact-size 1960 Series stainless nylon-insert part before quoting availability.
