Simpson Strong-Tie® Quik Drive auto-feed screw driving systems turn repetitive fastening into opportunities to increase efficiency and save time. Extensive research goes into the design of each system and screw to understand the intended applications, fastener performance demands and the workflow in which installations take place. This results in professional-quality auto-feed solutions that truly make work easier. The PRO300SG2 attachment was designed for decking on decks and docks, subfloor to wood or steel, wall plates, stair treads, sheathing and fiber-cement siding to steel applications.
