Key things to remember
The essentials from this document in plain words. Check the full document before you rely on a figure.
- 12 gauge, 24 TPI, lengths 32, 38, 50, 65, 85 and 100mm, flanged hex head 14.5mm across with a 5/16 inch drive. Drill point 15mm long.
- C1022 hardened steel with the X9 ProteXion coating, which the sheet rates as suitable for ISO 9223 category 4 environments.
- The extended drill point and fine 24 TPI thread let it drill steel up to 12mm thick. Uses: insulated roofing panels to steel, crest fixing on all roofing profiles, metal to metal fixing and metal roofing.
- Working pullout load in hot rolled steel: 1,600N in 3mm and 3,340N in 6, 8 and 12mm. 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 27kg load at 2,200 RPM it drills 8mm CRS plate in no more than 7 seconds on average (10 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: Steel fabricators, builders and roofers fixing into thick purlins and hot rolled steel.
