Lag Bolts for Wood
Lag Bolts for Wood
(OP)
I am designing the mount brackets to mount solar panels on a roof. I have calculated the pullout force to be 1260 lbs per bolt and can only use 2 bolts (i.e. total pullout from wind load is 2520 lbs). The bolts are to be 1/4" and mounted in Doug-Fir wood. This means I would need 5.5 inches of embedment in the wood. Does anyone know where you can get Lag bolts with 5 1/2" of thread?
Thanks for your help, Kevan

The fastener pictured in the above link is what I would call a coach screw.
