ABSTRACT:
The connector plate has a plurality of slender nail-like teeth struck to project at right angles to the plate for embedment into adjoining wooden members. The teeth are struck in longitudinal rows with the teeth in each row being staggered longitudinally relative to the teeth of next adjacent rows. The teeth in every second alternate row are struck such that the slots left thereby in the plate extend from the teeth in like directions while the teeth in the next adjacent alternate row in are struck such that the slots left thereby in the plate extend an opposed longitudinal direction to the slots formed in adjacent alternate rows. The teeth in the rows between such alternate rows are formed in longitudinally spaced pairs with each pair of teeth struck to jointly define a slot in the plate, the teeth being located at opposite ends of the slot. These paired teeth are shorter in length than the length of the teeth in adjacent rows and are twisted about their longitudinal axes when struck whereby increased resistance to withdrawal is effected. These short teeth have oppositely scarfed tips to provide a clinching action upon embedment into the wooden members. The tips of the longer teeth in the alternate rows are chisel-pointed providing optimum penetration characteristics upon embedment.
