1/4-28 x 1/2 is an alloy steel socket set screw fitted with a brass tip for machinery and tooling locations where surface marking must be controlled.

Typical uses include machine-tool stops on finished ways, fixture pads, and locating features used during setup. Buyers should confirm the tip material, thread fit, thread size, and threaded body length against the drawing before substitution. Brass gives a firmer metallic contact face when that contact style is preferred over nylon.

Cold Headers keeps alloy tipped set screws organized by thread, length, and tip material so the correct replacement can be found quickly. Nylon and brass tips serve different jobs: nylon gives the softer touch, while brass provides a firmer metallic face.
