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
• Torque 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 it works like new
• The hexagon is typically a smaller diameter than would be used with an external cap, and is more likely to round off its contact surfaces.
• It is much more difficult to turn a damaged (rounded or otherwise) internal fastener than an external one.
