5/16-24 x 1 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. 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. 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.
