Abstract
A system for locking together sheets of semi-rigid material. The system includes a clamp with a head having a clamp face, and a threaded rod having a first end affixed to the clamp face, and a second end that penetrates through the sheets. The system also includes a nut with a face forced into contact with the second side when tightened to the rod. The clamp face includes a gripping region, in a first circumferential position, with a trough and a hook that projects beyond the plane of the clamp face; and a leverage region, in a second circumferential position, that projects axially, so that, as the nut is tightened, the leverage region contacts the sheets' first side, and upon continued tightening, exerts a torque on the clamp head, elastically deforming the clamp so as to cause the hook to dig into the first side and prevent head rotation.
