Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose the 8 in. length for assemblies such as two layers of polyiso plus cover board over a deck needing deeper embedment; confirm pull-out on the actual deck. Drive square with an adjustable-clutch screwgun so heads seat without burying. Always install with the JM plate specified for the wind-uplift assembly.
Fastener points are sharp; wear gloves and eye protection and observe roofing fall-protection requirements.
