[50 PKG] Set Screws Socket Cup Point Nylon Patch Alloy Thermal Black Oxide 1/2-13 X 1 3/4

Designed for precise, secure fastening in machinery, fixtures, and tool setups, this Set Screws Socket Cup Point Nylon Patch Alloy Thermal Black Oxide 1/2-13 x 1 3/4 combines strength, surface protection, and vibration-resistance in a compact fastener.

With a cup point that provides a centered seating surface and high torque transfer, this screw minimizes slippage under vibration. The nylon patch beneath the head guards mating surfaces from scratching and marring, making it ideal for delicate components where surface finish matters. The alloy steel body offers high strength, while the thermal black oxide finish adds corrosion resistance and a low-glare, hardened surface for long-lasting performance. The 1/2-13 thread size and 1/4 inch 3/4 inch length suit a range of industrial applications.
