A fastener system consists of a fixing and a locking pin. In use, when the attachment has been accomplished using the fixing screw and tightened, the locking pin is inserted into the through hole in the fixing screw, to lock into position preventing removal of the screw. In a preferred embodiment the locking pin also prevents access to the method of removing the fixing screw by obscuring a driving formation of the fixing screw. |
