- Holds an object in place via friction between the point of the screw and the fastened material.
- While similar to set screws with a hex recess drive, the square head allows for a wrench to be used.
- Square head set screws are also known as grub screws.
- Alloy steel fasteners are significantly stronger than standard low carbon steel fasteners.
- Set screws are designed to be used under compressive stress only.
