12G-14 X 42MM SELF DRILLING HEX HEAD PACK OF 20 C4 TP156W

Self-drilling hex head top grip with EPDM sealing washer for fastening metal roof sheet to metal battens, steel purlins or other steel substrates. This screw is perfect in steel roof construction where a heavy duty roofing screw is required. Hardened steel self drilling point (tek) enables the tip to drill through up to 4.5mm mild steel. The flanged hex head 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 sheeting and prevents dimpling. ICCONS top grip threaded screws also come with upper shank protection the removes burrs that may damage the EPDM washer, and helps protect the galvanised coating on the upper thread. ICCONS Class 4 galvanised coating leaves little swarf (dust) for a quicker clean-up and high corrosion resistance.
