1/4-20 x 1 1/2 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert supports compact internal-hex fastening where a backed-out screw would create a service problem. 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. The 1960 Series name identifies the modern ASME B18.3 head-proportion standard for socket head cap screws, successor to the older 1936 series, not a year of manufacture.
