The PAMFast AutoFeed Screw-Driving Tool, which is designed to implant 50 screws from a collated strip, can be used for a wide range of construction-related tasks, e.g., subflooring, decking, drywalling, sheathing, tile roofing, steel framing, crating, pallet-making. It accommodates #6 to #12 screws that are 1 to 3 inches long and is powered by electricity or air compressor (depending on model). Its components include: a Milwaukee 2,500 RPM motor; a 20-inch universal extension that allows one to fasten from a standing position, an auto-feed attachment, and a keyless bit. Also provided are a carrying case, tool holder, and wrenches. Insertion depth is control by rotating the tool's adjusting ring, each click changing depth 1/64 of an inch. Disengaging the AutoFeed mechanism, it can be used as a conventional power screw driver.
