摘要

The device (10) has a hexagon head (11) adapted to an internal hexagon of hexagon socket screws, which are to be secured, where the head is firmly connected with a u-shaped curved claw clip (12), clip thighs (13, 14) and teeth (15) for detachable fixing of the head in a sinkhole. The teeth are pressed with initial spring tension against an inner wall of the sinkhole. The claw clip is made as a press-bent part from a high temperature-firm steel sheet, and from nickel90, and is firmly connected with the hexagon head by a pressing operation. Independent claims are also included for the following: (1) a method for assembling a screw locking device (2) a mounting tool for assembly of a screw locking device.
