5/16-18 x 2 1/4 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert fits replacement and production work where the exact stainless size and pellet feature matter. 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. The nylon element gives the joint a locking feature, but it also limits service temperature compared with an all-metal socket screw.
For rounded exposed heads with the same locking concept, review 18-8 Button Head Socket Cap Screws with Nylon Insert. 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.
