 Pentagon

A pentagon screw drive uses five-sided fastener heads. The fastener is known as a penta screw. They require a special five-point socket in order to be turned. Water meter covers, natural gas valves, and electrical cabinets are commonly secured with penta fasteners. It is also common in the U.S. for fire hydrants to have valves with a pentagon drive.

 Thumbscrew

A thumbscrew is a type of screw drive with either a tall head and ridged or knurled sides, or a flat, vertical head. They are intended to be tightened and loosened by hand. They are often cut for Phillips head or slotted screwdrivers as well.
