Manufacturing Process for Brass Screws

Brass machine screws are manufactured using precision cold heading and roll threading techniques to ensure high-quality and consistent threads. We also offer Brass SEMS screws with inbuilt washers where needed. Besides, we also offer Brass thumb Screws, Brass Chicago Screws, Brass paper fasteners, Brass Book Binding screws, Brass socket screws, Brass grub screws, Slotted grub screws  and socket head grub screws, Captive screws etc.

1. Cold Heading

  • Brass wire is cut to length.
  • The wire is forged into the desired head shape under high pressure.
  • Additional shaping and trimming are done for a uniform appearance.

2. Roll Threading

  • Threads are formed using a rolling process rather than cutting, which improves strength and durability.
  • Roll threading also enhances fatigue resistance and ensures accurate thread dimensions.
