ABSTRACT:
The disclosure herein describes a device for fastening objects to thin or hollow walls which comprises: a bolt, a nut with an aperture, a guide blade mounted to the bolt and extending lengthwise thereof and a bascule mounted to the bolt and interconnected to the nut; pivotal movement of the bascule on and relative to the bolt is caused by the nut being threadedly displaced along the shank portion of the bolt as a result of the screw being rotated; the guide blade extends through the aperture of the nut and prevents it from rotating with the screw.
