5/8-11 x 2 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert serves equipment that needs top-side socket access and a built-in prevailing-torque feature. The insert is positioned in the threaded body so the screw can develop prevailing torque during engagement.
Typical applications include processing equipment, maintenance repair, and replacement fastener work, where the exact thread and length help match drawings, service records, and replacement needs. 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.
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 has supplied specialty socket fasteners since 1962 and helps source exact stainless sizes and uncommon lengths. 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.
