ABSTRACT:
A mounting assembly includes an expansible anchor having a threaded bolt, an expansible sleeve, and a shank member having an internal thread that enables the shank member to be screwed onto the threaded bolt to provide for expansion of the expansible sleeve over the expander body of the threaded bolt. The mounting assembly also includes a mounting tool adapted to be clamped in a drill chuck of an impact drilling machine and the like and having an end portion shaped like a polyhedron for engaging the internal bore of the shank member which internal bore has a diameter that is less than the diameter of the internal thread.
The internal bore and the polyhedron end portion has lateral faces and edges such that, when the mounting tool clamped is engaged with the internal bore and the drill operated, the shank member rotates with the mounting tool until the installation is complete.
