5/16-18 x 1 1/4 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. Nylon contact at the thread adds frictional resistance while preserving the standard internal hex drive arrangement.
Use it for packaging machinery, motion guards, or access panels after confirming thread engagement, drive access, and the mating material. Because 18-8 is not heat-treated for maximum clamp load, compare the 1960 Series Alloy Steel SHCS with Nylon Insert when joint strength is the governing requirement.
Use the exact thread, length, pellet diameter, and pellet location when matching drawings or service records. Cold Headers can help confirm the exact-size 1960 Series stainless nylon-insert part before quoting availability.
