I just bot some joisthangers. Instead of the usual punch holes, these have flared material that pretty much dictates that any nailing will be toenailed, instead of straight in. Is this 'better?'
Yes, Nail the hangers on with teco nails, then toe nail the joists with 12d nails thru the punch outs. This just saves the step of toenailing the joists and then putting hangers on with tecos.
