Expert Verdict — Reviewed by the SuperArbor Pro Desk
An 11 in. fastener is appropriate for thick insulation assemblies; always verify holding power with a fastener pull test on the actual deck before full installation. Install perpendicular to the deck and into the top flutes of steel decks for best performance. Avoid overdriving, and pair with the Carlisle-approved plate required by your project specification.
Wear eye protection during drilling and installation, and avoid overdriving the fastener.
