Fastening system for fastening plate element made of aluminum oxide at base element made of steel sheet, has stopper element undetachably screwed into continuous hole formed in wear protection element by external thread of stopper element

摘要

The system (10) has a bolt element (16) e.g. weld bolt, applied on a base element (14), and projecting into a continuous hole (18) formed in a wear protection element (12). The hole is closed by a wear-resistant stopper element (20) at a side, which faces away from the base element. A spring disk element (26) is clamped between an external thread section (22) of the bolt element and an internal thread (24) of the hole. The stopper element is undetachably screwed into the hole by an external thread of the stopper element. The base element and the bolt element are made of metal.
