Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match fastener length to deck type and thickness: Carlisle recommends conducting a fastener pull test to evaluate deck conditions before committing to fastener length. Install perpendicular to the deck and into the top flutes of steel decks for optimum performance. Avoid overdriving the fastener, and pair with the correct Carlisle-approved plate for the membrane attachment pattern specified in your project details.
Wear eye protection during drilling and installation, and avoid overdriving the fastener.
