4-40 x 5/16 is part of Cold Headers' alloy tipped set screw range, pairing a socket-drive alloy body with a soft brass contact face.

Typical uses include lead screws, ball screws, racks, and adjustment stops that are reset during setup. Because the tip is the contact element, the mating material and acceptable witness mark should guide final selection. Brass gives a firmer metallic contact face when that contact style is preferred over nylon.

Cold Headers' tipped-screw program is built for buyers who need the right contact face without losing the reviewed thread and length. If the environment calls for a stainless body, the Nylon and Brass Tip 18-8 Stainless Socket Set Screws category is the related catalog path.
