For exact-size replacement work, 4-40 x 1/4 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 internal socket drive keeps installation compact and leaves no external head projecting from the assembly. Brass gives a firmer metallic contact face when that contact style is preferred over nylon.

Cold Headers brings decades of socket fastener experience to tipped screws used in maintenance, production, and repair work. For maximum bite instead of surface protection, the related cup point alloy set screw family is the better comparison.
