    Self-drilling roofing screw with a Dune colour-matched head and a watertight neo seal.

    Fixing steel roof or wall sheeting is no place for a screw that strips the hole or rusts out a season later. These are the ones that hold.

    The Tornado self-drilling screw bites straight into metal or steel batten with no pre-drilling, and the bonded neo washer seals the hole against water. The head is finished in Dune to match your Colorbond sheeting, so the fixing line all but disappears once the roof is up.

    A Class 4 galvanised coating means it stands up to our weather without weeping rust down a fresh wall. Right for roof crests and wall cladding.
