Washer, in particular to be used for joining painted metal parts, comprising raised upper and lower inner edges

摘要

The connection between an auxiliary and the main frame of a lorry cannot be created by welding. The screw used for the purpose is guided through a washer (1) at both sides of the parts to be joined and secured with a nut. The chamfered inner edge (10, 15) of the upper surface (5) of the washer (1) is slightly raised in relation to the also chamfered outer edge (12, 14). The lower surface (7) is complementary shaped and positioned parallel to the upper surface (5).
