Self Drilling Hex with 25mm Multiseal Washer - Coarse Thread
Self-drilling hex head panel screw with 25mm Multiseal sealing washer for fastening metal insulated roof and floor panels to metal battens, steel purlins or other steel substrates. This screw is perfect in panel construction where the material thickness and steel substrates are too thick for a standard roofing screw (Roof Stars). Hardened steel self drilling point (tek) enables the tip to drill through up to 4.5mm mild steel. The flanged hex head accompanied with the Multiseal washer lends to high pull-out strength and a class 4 galvanised coating results in strong corrosion resistance. Top grip thread ensures a secure hold on the panel and prevents dimpling. ICCONS Class 4 galvanised coating leaves little swarf (dust) for a quicker clean-up and high corrosion resistance.
