What are the Different Types of Screws? Hex: There are two types of screws that have hex heads — one that has a hexagonal recession in the head and one that does not have any grooves or slots at all. A hex socket screw or Allen screw requires the use of an Allen wrench, which has a hexagonal shaft that is inserted into the recession in the screw head. The other type of hex screw has an entire head that is hexagonally shaped. A wrench set, socket wrench or adjustable wrench is required for driving hex screws. Square: Also know as a Robertson screw head, it has a square indentation to minimize slipping. It also requires a special driver for tightening and loosening.
