Key things to remember
The essentials from this document in plain words. Check the full document before you rely on a figure.
- 14 gauge, 10 TPI, lengths 55, 65, 75 and 95mm, hex head with a 3/8 inch drive. The washer is 25mm across.
- C1022 hardened steel with the X9 ProteXion coating, which the sheet rates as suitable for ISO 9223 category 4 environments.
- Uses: metal roofing and wall cladding, crest fixing and metal to metal fixing.
- Working pullout load: 350N in G2 steel 0.8mm, 2,400N in G450 2.0mm and 3,000N in G2 3.0mm. The sheet also lists mean and characteristic test loads, but does not say how the working loads were derived, so treat them as a guide only.
- Drill point test: under a 18kg load at 2,200 RPM it drills 2.0mm 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.
Who it helps: Roofers and builders fixing metal roofing and cladding to steel, and staff checking sizes or pullout figures.
