Expert Verdict — Reviewed by the SuperArbor Pro Desk
The 18 in. HP-X suits deep assemblies such as thick insulation stacks over corrugated steel, where the fastener must reach the deck through multiple layers. Drive perpendicular to the deck and into the top flutes of steel decking for best pull-out performance, and avoid overdriving. Because deck strength varies, run a fastener pull test on the actual deck before finalizing the fastening pattern.
Wear eye protection during drilling and installation, and review Carlisle specifications and local code requirements for the fastening pattern.
