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, 50 and 75mm long with a plain shank, hex head 15mm across with a 3/8 inch drive.
- C1022 hardened steel with the X9 ProteXion coating, which the sheet rates as suitable for ISO 9223 category 4 environments.
- Uses: metal to metal fixing, fixing wall cladding to steel purlins and battens, crest fixing and metal roofing.
- Working pullout load: 350N in G2 steel 0.8mm, 2,400N in G450 2.0mm and 3,000N in G2 3.0mm. 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 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: Builders, fabricators and roofers choosing a self-drilling screw for steel, and staff checking sizes or pullout figures.
