Expert Verdict Reviewed by the SuperArbor Pro Desk

Match fastener length to panel plus purlin or deck thickness so at least one inch of thread engages the substrate. The #15 drill point suits heavier-gauge steel where smaller points can burn out. Order roughly one screw per panel lap plus fastener-spacing requirements, and remember 1,000 per box makes it easy to cover a large job.

Wear safety glasses and gloves when driving self-drilling screws; drilled metal chips and shavings are sharp.
