Holes need to be drilled 1/8" larger than thesnap tie head. Normally a 9/16" diameter drill bit willbe required. We recommend you drill a maximum 5plywood panels.The 5/8" take-up of the eccentric on theJahn "A" Bracket allows a snap tie with a L&W dimensionof 4-3/4" to be used with a 5/8" or 3/4" plywood. The 5/8"take-up on the "C" bracket allows it and 81/4" snap ties tobe used on 5/8" plywood.Gang Drillingof PlywoodSnaptie Spacing and Rate Placement:The most common snap tie spacings being used with the Jahn Forming System are shown below.
