Expert Verdict — Reviewed by the SuperArbor Pro Desk
Reserve the 10 in. HP-X for thick multi-layer insulation stacks where Carlisle's minimum penetration into steel or wood deck is still achieved; the fastener carries 4 in. of thread on this size. Drive perpendicular to the deck, into the top flutes of steel decks, and avoid overdriving. Confirm the length with a pull test or deck check on unfamiliar buildings.
Wear eye protection during drilling and installation, and take care not to overdrive the fastener.
