For exact-size replacement work, 1/2-13 x 3/8 identifies the thread, threaded body length, and brass tip material in a single set screw listing.

Typical uses include robotics joints on finished shafts, compact pivots, and controlled-contact positioning details. 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.
