Corrosion protection coating – the galvanised hex head and the washer of the metal roof screws are coated with a weather-resistant layer that effectively prevents rust on the exposed roof.
EPDM washer – Metal roof screws with EPDM washers provide good sealing performance and are tightened well in corrugated roofs, preventing leaks in storms.
AGGRESSIVE HIGH-DEEP THREAD – Galvanised self-tapping screws have alternately high and low threads to minimise cracks and crevices when screwing in and grip firmly into sheet metal and wood panelling.
