InnoviFast™ Heavy Duty (HD) Fasteners are used for easy installation of IKO Innovi™ TPO thermoplastic polyolefin single-ply roofs. InnoviFast Heavy Duty (HD) Fasteners are #15 fasteners for attachment of membrane, insulation, cover board and metal terminations. The 13 threads per inch (26 mm) provide for high pull-out values for steel, wood and structural concrete decks. The fasteners have a cathodic epoxy E-coating for resistance to humidity and cyclic corrosion. InnoviFast Heavy Duty (HD) Fasteners' drill point design prevents fastener walking and cuts through gravel and BUR. InnoviFast Heavy Duty (HD) Fasteners are important components in the successful installation of an IKO InnoviTPO commercial roofing system and can help qualify for an appropriate IKO Diamond Shield Limited Warranty.
