ABSTRACT:
A non-rotating toggle bolt assembly which includes a collapsible toggle threadably received on the shank end of a bolt whose length is greater than the thickness of the wall for which the assembly is intended. When the toggle is collapsed, it assumes reduced dimensions to permit its passage through a hole drilled in the wall. On emerging from the hole at the shank end of the bolt, the toggle which is now displaced from the inner surface of the wall, resumes its normal dimensions. The assembly is provided with means which act to prevent rotation of the toggle when, in the course of installation, the operator turns the bolt to advance the toggle on the shank into engagement with the inner surface of the wall to fasten the assembly thereon.
