On a wet fall day, our founder Kevin was working on a ladder to screw trim onto a greenhouse. Reaching overhead to hold the trim while driving tek screws and dropping far more than were installed proved to be a memorably frustrating experience. Why hadn't someone created better tool to prevent this frustration? This experience cemented a commitment to solve the age-old challenge of screws falling off the bit or driver when installing. We're happy to offer this solution to the skilled trades and craftsmen around the world! Stop dropping screws, free up your second hand and get more done! To use: Easily push a screw into the bit and watch the device automatically lock onto the screw. Drive the screw with confidence and watch it release automatically when installed. The driver is ready to load the next screw (you dont need to touch the driver to achieve any of this). New Revolution Tools developed and manufactures the AutoLock line of screw driving tools that lock onto the head of screws mechanically.
