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
