Expert Verdict — Reviewed by the SuperArbor Pro Desk
For mechanically attached single-ply assemblies over concrete, choose the fastener length to cover plate thickness plus insulation plus at least 1 in. of embedment into a minimum 2,500 psi deck. Pre-drill the pilot hole deep enough that the fastener tip never contacts accumulated dust, and check pullout values if you substitute the 7/32 in. bit. Pair with the matching Carlisle fastening plates and follow Carlisle specifications and details for fastener patterns.
Eye protection is recommended during drilling and installation of fasteners; review Carlisle specifications and details for complete installation information.
