For adjustment locations that are loosened and reset, 3/8-24 x 1/4 uses a brass tip so the replaceable face takes the contact instead of the mating surface.
Typical uses include polished shaft collars, small hubs, and replacement collars on finished round stock. The soft tip concentrates contact at the end of the screw while avoiding the harsher bite of an untreated alloy point. Brass gives a firmer metallic contact face when that contact style is preferred over nylon.
For uncommon lengths or fine-thread tipped screws, Cold Headers supports exact-size sourcing without changing the specified tip material. 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.
