Self-Locking Screw Connection
First Claim
1. A screw connection comprising:
- a threaded screw section,a polygonal nut screwed on the screw section,an intermediate washer, which is secured against rotation relative to the screw section and is rotatably mounted on the nut, said intermediate washer comprising a grid disposed on the circumference thereof, andat least one catch made of a resilient sheet-metal component mounted on the nut such that when a wrench is applied to the nut, said at least one catch is compressed and drawn out of engagement with the grid so that the nut can be freely turned, and when the wrench is removed from the nut, the catch moves into engagement with the grid to lock the nut against rotation relative to the intermediate washer and the screw section.

Abstract
A screw connection having a screw section and a nut threaded thereon. A self-locking effect of the nut on the screw section is achieved in a simple manner in that an intermediate disk is supported non-rotatably on the screw section and is received on the nut so as to be rotatable relative to the nut. The intermediate disk includes a grid distributed around the circumference of the intermediate disk, and the nut carries at least one resiliently elastic, radially displaceable catch formed by a sheet-metal part which, after installing the nut, positively engages the grid to lock the nut against rotation relative to the screw section and intermediate disk. Upon application of a wrench to the nut, the at least one resilient, radially displaceable catch is compressed and drawn out of engagement with the grid, so that the nut can be rotated relative to the screw section.
