Polycarbonate Roof Fasteners Series

POLY-FAST™ fasteners features a cutting washer to create a much-required thermal expansion hole on plastic profiled roofing panels, which is then securely fastened onto the purlin support underneath in one-go.  A nominal 11mm diameter thermal expansion hole is created during the process.  The cutting washer also functions as stopper when mated with serrated knurls on the shank, preventing screw over-run or over-drive, and squashing of the raised profile.  A large domed BAZ with two concentric sealing rims on the washer underside completes the package – the domed structure providing superior strength against high winds, and two concentric sealing rims keeping the expansion hole fully sealed.
