5/8-11 x 2 3/4 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert provides a cataloged stainless option for cap-screw joints that specify a nylon locking element. 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. 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. 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.
