Expert Verdict Reviewed by the SuperArbor Pro Desk

Match fastener length to your insulation thickness plus penetration into the deck; the 14 in. size suits very thick assemblies on wood or 22-gauge-plus steel. Always pair with the correct Carlisle fastening plate and follow Carlisle’s fastener density requirements on Sure-Tough systems to maintain pull-out values and warranty coverage. The FM 4470-surpassing corrosion protection makes these suitable for long-term exposed-plate details.

Use the proper driver bit and eye protection, and keep fingers clear of the screw point and fastening plate while driving.
