Key things to remember
The essentials from this document in plain words. Check the full document before you rely on a figure.
- 14 gauge, 14 TPI, lengths 125, 150, 175, 205 and 230mm, hex head with a 3/8 inch drive. Assembled with a 25mm aluminium bonded washer.
- C1022 hardened steel with the X9 ProteXion coating, which the sheet rates as suitable for ISO 9223 category 4 environments.
- For fastening metal roofing sheets to steel frames in high wind areas; the longer lengths suit different thicknesses of roofing insulation. Suits all roofing profiles and sheds.
- Working pullout load: 400N in G2 steel 0.7mm, 2,250N in G450 1.9mm and 3,000N in G2 2.9mm. The 2.5 factor of safety for steel is already included; the mean and characteristic loads beside them are test values. All values come from laboratory tests, and real pullout can differ with the base material.
- Drill point test: under a 18kg load at 2,200 RPM it drills 1.9mm G450 plate in no more than 5 seconds on average (6 seconds at most for any one screw).
- Drive with a cordless screw gun at 2,200 to 3,000 RPM using a hex drive bit, with firm, steady pressure, and do not over-tighten. Impact drivers are not recommended.
