Furring strip screw recommendations
Assembly = 2″ zip R (1.5″ polyiso + osb) with 1x furring strips. If I were to go for 1.5″ penetration I need min of 4.25″ screws, I see that headlock says min of 2″ penetration so that would give me 4.75″. So it seems like I need a 4-1/2″ or 5″ screw.
Fastenmaster has headlock 4-1/2 inchers (1/4″ short but I think it’d be ok) but looks like they’ll run me about $0.33 each, given the qty required this hurts. Any recommendation for what others are using for this application/length?
