Expert Verdict — Reviewed by the SuperArbor Pro Desk
Select fastener length by totaling the assembly thickness plus the 1 in. minimum embedment into the deck; when in doubt, go one step longer rather than short. The locking staple design helps resist back-out in gypsum and LWIC, where smooth-shank fasteners can loosen. Always follow the membrane manufacturer's fastener pattern and pull-test the deck first to confirm holding power.
Impact-driving fasteners can eject shavings and staples; wear safety glasses and gloves, and keep hands clear of the tool tip.
Order GAF Drill-Tec Locking Impact Nails in the length and box count your deck assembly requires.
