Screw Vortex Roof Hex Seal C4 M6.2-13 X 50 Headland

Roof Stars, Roof Zips and Vortex are 3 of the brands names of this self-drilling timber and metal point screw with an EPDM sealing washer for fastening metal roof sheet to thin metal battens, purlins, and timber battens, making this screw first choice for steel roof construction. The universal self-drilling point enables the screw to drill through light gauge mild steel and timber. The flanged hex head lends to high pull-over strength and a class 4 galvanised coating results in strong corrosion resistance. Top grip thread ensures a secure hold on sheeting and secures the sheet better to prevent dimpling when roofers are walking in the roofs sheet. The upper shank protection creates a clearance hole that protects the EPDM washer and helps protect the class4 coating on the upper thread.
