3/8-24 x 1 1/2 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. Its locking element supports service where a standard all-metal cap screw may need an added thread-locking feature.
This size is often reviewed for bottling lines, guide rails, and cleaning-cycle equipment 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 torque-once joints where a locking pellet is not required, plain 18-8 Socket Head Cap Screws may be the simpler routing. 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.
