<p>Conventional fixing screws (17) inserted into through-holes (15) of the frame (11), are locked against longitudinal displacement while maintaining the ability of rotation, by means of a locking washer (1) that is inserted in the hole part (21) countersunk for the head (19) of the respective fixing screws so as to be in contact with the head of the fixing screw, the locking washer then being locked relative to the wall of the hole. The locking washer has a centre hole (5) through which the fixing screw can be rotated by means of a screwdriver in order to adjust the position of the frame relative to the element (13) into which the fixing screw is screwed, said element delimiting the opening. A locking washer (1) for carrying out the method comprises plateshaped barb elements (7) projecting in one direction from a ring element, the barb elements being brought into engagement with the wall of the hole by means of a plunger (23).</p> |
