I need to use carriage screws with bolt heads through hole in a steel frame to underside of new wood stair treads The screws will be m8 or 10 and 30mm long. Is there something like an electric screwdriver to tighten them as I will be working by touch only on the lower ones near the floor and bolting them upward. I dont relish the thought of using an ordinary spanner on the 100 plus screws that will be needed
