ABSTRACT:
A post has flanges with inturned beads which form a narrow mouth, the beads being engaged by a non-circular head on a screw such that rotation of the head in one direction releases its engagement from the beads, and the panel member or frame member to be assembled to the post has a nut contained within a nut receiving cavity, the nut threadably engaging the screw so as to firmly clamp the member to the post.
