What matters when driving Torx screws into dense lumber Dense hardwood, pressure-treated lumber, and dry framing stock put more resistance on a screw than ordinary softwood. An impact driver can supply the bursts of torque,…
Stair treads put unusual demands on an impact driver. The screws are often long, the hardwood can split near an edge, and a slipping bit can leave a visible scar. You want enough power to…
