ABSTRACT:
A toggle bolt assembly that includes a flexible elongated strip that is hung upon the bolt so that the strip loops over the winged trunnion nut. One end of the strip is hung between the nut and the wings while the opposite end of the strip is hung between the bolt head and the nut. The opposite end of the strip is expanded so that it can be wedged tightly into the clearance hole formed in a hollow through which the wings are passed in assembly. The wedged strip holds the unfolded wings in a non-rotating condition inside the wall.
