Information About

Set Screw




Imagine a sleeve or metal pipe. Now put a loose-fitting bar inside that sleeve. They slide relative to each other, don't they? How would you prevent them from sliding? Well, you might make a small threaded hole in the outer sleeve, put a Screw in it, and tighten it until it presses against the inner bar and stops the two from sliding. That screw is called a set screw. Set screws are also used to secure gears and wheels on shafts, preventing both sliding and rotation.

Set screws appear with a variety of tip types;
  • Flat Point

  • Domed Point

  • Cone Point

  • Cup Point

  • Knurled Cup Point

  • Dog Point


They also appear with a variety of drive styles —

In British parlance they are often called grub screws.
