Fastener, to hold components together with an elastic tension, has a nut with a one-piece flange to bear against the lower component when tightened on the screw bolt and press against it with a spring action

摘要

The fastener (1a), to hold components (2,3) together with an elastic tension, has a screw bolt (4) through passage openings (5,6) in each, and a spring nut (7). The bolt head (8) has a shoulder (9), wider than the bolt thread (10), which passes through the passage openings to bear against a flange (11) in one piece with the nut. The edge (12) of the flange bears against the lower component, to be bent away as the nut is tightened on the bolt thread. The nut and flange are a one-piece injection molded plastics component.
