12g-14 x 37mm - 1000pc Double Grip Self Drilling Roofing Screws Galvanised Class 4

Galvanised Double Grip Self Drilling Roofing Screws have a hardened self drilling point which cuts through mild steel without the need for pre-drilling. However for thick or hardened steel pre-drilling may be required. The hex head enables a fast, secure drive into the steel. The Class 4 galvanising meets Australian standards for use in roofing. The Neo washer helps give a water tight seal and the double grip allows extra fixing into corrugated roofing.
