摘要

The screw (2) has one or more splits in or on the threaded neck or even in the head of the screw. A stop washer (1.1) or a stop for the threaded connection to the bolt (1.2) seated on it can be pushed onto or into the split screw. An independent claim is included for a locking device (3.1) for the stop washer with the threaded connection, whereby the split plate (1) with the threaded connection and one or more nuts or a mating piece for screws/threads are assembled as a unit, with the locking device on the split bolt.
