Abstract: A one-piece boardlock formed from an elongated metallic strip comprises a vertical mounting portion, and an integral horizontal portion extending from one end of the vertical portion. At the end of the horizontal portion remote from the vertical portion a pair of side legs are formed from two laterally spaced side portions by three successive right-angle bends so that the side legs project perpendicularly from the strip. Similarly, a pair of auxiliary legs are formed from an intermediate portion of the horizontal strip portion by stamping and bending. These four legs are positioned symmetrically around a central axis perpendicular to the horizontal strip portion. An outwardly inclined cam surface is provided adjacent each leg end, and an inwardly inclined cam surface is positioned intermediate the outwardly inclined cam surface and each leg end.
