1/4-28 x 1 3/4 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert is selected when stainless hardware and thread-friction locking are needed in the same fastener. Nylon contact at the thread adds frictional resistance while preserving the standard internal hex drive arrangement.
Use it for conveyor side rails, machine covers, or adjustable production fixtures after confirming thread engagement, drive access, and the mating material. The 18% chromium and 8% nickel austenitic stainless material is used for general corrosion resistance and a clean appearance in ordinary industrial environments.
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.
