Socket set screws, also known as grub screws, have no head and are typically tightened or loosened with a square or hex key. A slotted set screw can be adjusted with a screwdriver. Socket set screws prevent movement of a pulley or similar machine part relative to a shaft. A cup point set screw has a rounded tip that grips and resists deforming the shaft surface. A flat point screw provides more contact with the shaft.

Knurled cup set screws feature one slight variation from the cup point set screw. This style has serrated ridges, or knurls, in the indented cup that bite into the contact material and effectively lock in place for a powerful grip that resists loosening caused by vibration. As with the cup point, a certain amount of scarring on the surface of the contact material is likely. Knurled set screws should not be re-used because the knurled ridges suffer damage upon removal and therefore offer less strength upon re-setting.
