Product Description
For use with the SPAX timber to steel decking screws.
Pre-drill the timber boards with a SPAX Step-drill 5. There is no need to pre-drill the steel, as the specially designed tip of the Timber-to-Steel Screw will pre-drill steel up to 5mm thick (minimum recommended steel thickness is 1.6mm). Adjust your SPAX Step-drill 5 so that when the tip hits the steel joist, the step bit cuts 1-2mm into the surface of the board.
