Expert Verdict — Reviewed by the SuperArbor Pro Desk
Select 7 in. length when fastener stack-up (membrane, plate, insulation thickness plus deck engagement) requires it; Carlisle specifies minimum deck penetration. Install perpendicular to the deck and into the top flutes of steel decks for optimum performance, and avoid overdriving. On decks of uncertain condition, run a fastener pull test per Carlisle recommendations before full production.
Wear eye protection during drilling and installation, and take care not to overdrive the fastener.
