Hex key or Allen key (also known by various other synonyms ) is a tool of hexagonalcross-section used to drive bolts and screws that have a hexagonal socket in the head (internal-wrenching hexagon drive)

Some features of hex keys are:

• The tool is simple, small and light
• The contact surfaces of the screw or bolt are protected from external damage
• There are six contact surfaces between bolt and driver
• The tool can be used with a headless screw
• The screw can be inserted into its hole using the key
• Torgue is constrained by the length and thickness of the key
• Very small bolt heads can be accommodated
• The tool can be manufactured very cheaply, so one is often included with products requiring end-user assembly
• Either end of the tool can be used to take advantage of reach or torque
• The tool is L-shaped
• The tool can be reconditioned using an electric grinder by removing the worn-out part, and then works like new
