Panel fastener with threaded wall bolt

摘要

The bolt (1) can be screwed into a masonry borehole (2) by a tool engaging its front face. Its free end section (3) carries an outer thread (4), by which it can be screwed into an inner thread (6) of an end section (7) of a tubular adaptor (5), whose outer wall (8) has a toothing (9). The toothing anchors the adaptor rotatably, but not slidingly, in a bore (10) of the panel (P) to be fixed. The other adaptor end section has a polygonal socket with at least three edges. Pref. between the inner end of the inner thread and the socket the adaptor has a restricted tubular section with inner thread.
