1/4-28 x 1/4 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. Nylon contact at the thread adds frictional resistance while preserving the standard internal hex drive arrangement.
This size is often reviewed for beverage filling equipment, changeover tooling, and stainless guide assemblies when a stainless cap screw must retain a familiar socket head form. 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 countersunk installations, 18-8 Flat Head Socket Cap Screws with Nylon Insert keep the locking feature in a different head style. Since 1962, Cold Headers has helped buyers locate specialty socket fasteners for production, repair, and distributor requirements. 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.
