<p>The connector plate (100) has a rigid, planar base (102), and a plurality of adjacent elongated slots (108) defined in said metal plate (100). The slots (108) are offset in a sinusoidal pattern having at least one cycle with a maximum amplitude slot position, a minimum amplitude slot position and at least two zero-point slot positions. Each slot (108) has first and second reverse-oriented mirror-image teeth (104, 106) extending from the plate (100) at opposing ends of each slot (108). A punch (302) having a base portion (308) having a longitudinal axis (310) and a shank (304) having a longitudinal axis (306) offset from the base portion longitudinal (310) axis is also provided.</p> |
