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. At 10 in., these suit tall insulation stacks where the fastener must reach the specified penetration into the deck. Drive squarely with a clutch-adjusted screwgun so heads seat 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.
Order the Johns Manville #14 x 10 in. All Purpose fasteners, 500-carton, for your commercial roofing attachment package.
