General Rule for fixing to Concrete Material thickness + 25mm = Drive Pin Length e.g. 45mm timber + 25mm = 70mm Drive Pin Max Overdrive = 5mm Embedment Depth = 22-28mm For Fixing into Steel with a Parallel Shank Drive Pin
General Rule for fixing to steel Material thickness + Steel thickness + 6mm = Drive Pin Length For Fixing into Steel with a Stepped Shank Drive Pin
General Rule for fixing to steel up to 8mm thick Material thickness + Steel thickness + 6mm = Drive Pin Length
General Rule for fixing to steel over 8mm thick Material thickness + 10mm = Drive Pin Length
