The Hinge Screw is used to prevent closed doors from being removed from their hinges when the hinge pins are removed.  A screw is removed from the door side of the hinge and the corresponding screw from the jamb side.  The jamb side or door side (whichever is most convenient) then receives the Hinge Screw.  When the door is closed the protruding head of the screw enters the corresponding screw hole on the other hinge plate thus not allowing the hinges to pass one another  when the hinge pins are removed.  For use in steel or concrete frames use an appropriate sized expanding plug.

Our screw is adjustable to various penetrating depths into the jamb and the door.  The reason for this is to allow the screw to penetrate to a maximum depth into the door and frame so that it may be protected by the BOLT BUDDY on the frame and door.
