Where a standard pointed set screw would be too aggressive for the mating part, 4-40 x 3/8 offers a brass tip on an alloy steel socket set screw body.

Typical uses include semiconductor tooling, electronics fixtures, and light mechanical assemblies with finished contact surfaces. These parts are often selected where repeat adjustment matters and the mating surface is more valuable than the replaceable tip. Brass gives a firmer metallic contact face when that contact style is preferred over nylon.

Cold Headers applies nylon and brass tips in-house, which keeps the contact-face detail tied closely to the socket fastener itself. The 3A thread fit keeps the screw in the precision set-screw class while the tip changes the way the end contacts the part.
