This contractor-tough autofeed screw gun is ideal for those “standing jobs” such as decking and subflooring. The powerful 2500 rpm motor screws 1” to 3” collated screws in no time! Unlike nailing or stapling, attaching deck boards and subflooring with screws is the way to go. No squeaking or nail pull outs ensure a long lasting deck/subfloor project with no problems. Collated screw system uses 50 screws in one strip.
