Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pick the fastener length so it reaches and engages the steel deck without bottoming out; the 1-1/4 in. length suits thinner single-layer boards and the 2 in. length covers thicker or multi-layer insulation build-ups. Drive with a depth-setting screw gun so heads seat flush without stripping. Always match fastener and plate to the roofing system's tested assembly rather than substituting.
Self-drilling screws can shatter under excessive torque; wear eye protection and follow safe roof access and fall-protection requirements during installation.
