ABSTRACT:
There is provided a fastener for forming lap-type joints wherein a sheet metal plate has a plurality of teeth projecting in a substantially perpendicular direction from both sides of the plate. On one side of the plate the teeth are in rows of single teeth and on the opposite side of the plate the teeth are in rows of pairs of teeth. The ends of the single teeth are such that upon movement into a nailable member the teeth remain substantially perpendicular to the plate, while the ends of the paired teeth upon movement into a nailable surface are displaceable from the perpendicular direction and accomplishing a clenching between adjacent paired teeth. The paired teeth are of smaller cross-sectional area than the single teeth and may be placed into relatively fragile or thin material to provide secure fastening thereof to a more substantial material, e.g. wooden studs and the like.
