Expert Verdict — Reviewed by the SuperArbor Pro Desk
All Purpose fasteners are JM's general-use commercial roofing screws for mechanically attaching insulation, cover boards and membranes. Choose length so the fastener penetrates the deck to the depth the system specification requires - 14 in. suits deep insulation stacks over thick decks. Match drive torque so the head seats without stripping, and pair with the plates or sizes called out in the JM assembly spec.
Follow the fastener count, spacing and deck penetration specified by the roofing system manufacturer and local code, and wear eye protection when driving fasteners.
