ABSTRACT:
An anti-tamper fastening screw has an actuating head which can be accessed only by a special tool and can thus be used effectively in a locking system provided for use with removable automobile roof latching mechanisms. The threaded screw has a specially keyed and tooled head adjusted to be inserted through two holes and held in position by mating threads to retain a roof component in locked position. A special tool is provided which is operatively engageable with the keyed head of the fastening screw to prevent unauthorized removal of the detachable roof without utilizing the special tool.
