For exact-size replacement work, 1/4-28 x 5/8 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. The alloy body is the dry-service workhorse choice when the bill of material calls for an alloy socket set screw with a soft face. Brass gives a firmer metallic contact face when that contact style is preferred over nylon.
Cold Headers installs nylon and brass tips at its Chicago facility for set screws and cap screws when a tipped configuration is required. Because the tip is the contact element, the mating material and acceptable witness mark should guide final selection.
