Key things to remember
The essentials from this document in plain words. Check the full document before you rely on a figure.
- 14 gauge, 20 TPI, lengths 150, 200, 250 and 300mm, hex washer head 15mm across with a 3/8 inch drive. Drill point 16mm long, with an 8mm XGRiP thread section.
- 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 20 TPI thread let it drill steel up to 12mm thick. Uses: insulated roofing panels to steel, crest fixing on all roofing profiles, thick steel purlins, hot rolled steel and sheds.
- Working pullout load: 1,900N in G450 steel 2mm, 5,900N in G450 5mm, 7,450N in hot rolled steel 5mm and 8,950N in hot rolled steel 6mm and 8mm. 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 24kg load at 2,200 RPM it drills 2.5mm 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 insulated roofing panels to thick steel purlins.
