Set screw
*** Shopping-Tip: Set screw
A '''set screw''' is a type of
screw that exerts its clamping force through the bottom tip that projects through an open thread hole rather than a with larger head that remains outside.

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 —
*
Allen wrench Allen (hex)
* Square head
* Slotted
*
Bristol Wrench Bristol® spline
In British parlance they are often called '''grub screws'''.
