- Drilling capacity: steel purlin from 1.2mm to 5.0mm.
- Screw strength: tensile 13,360N, shear 7,340N, torsional 13.2Nm.
- Ultimate pull-out strength from G450 steel, characteristic (95% of results expected above it) and not a working load: 2,160N in 1.20mm, 3,270N in 1.50mm, 6,580N in 2.40mm. The sheet says safety factors must be applied for design.
- Install with a 5/16 inch hex nut setter in a cordless screw gun at 2,200 to 3,000 RPM, with firm pressure while it drills. Do not over-tighten.
