Industrial Screwdrivers and Screwfeeders

Industrial screwdrivers and screwfeeders are automated tools that are used to turn screws while providing close control of screw torque. Pneumatic devices use compressed air and are suitable for low-torque applications such as woodworking or sheet metal repair. Electric devices use AC or DC power and are designed for applications that require higher levels of torque. For both types of industrial screwdrivers, actuation methods include buttons, triggers, levers, and press-down heads or bits. Screwdrivers with both forward and reverse motions are commonly available. Clutches use continuous or discontinuous drives. Industrial screwdrivers that use continuous drive clutches deliver power continuously and without interruptions. These devices are usually gear-driven and include both external torque control and an automatic shut-off function. Industrial screwdrivers with discontinuous drive clutches deliver power in short bursts, but do not provide torque between bursts. Some devices generate torque with a small chamber of oil. Others generate torque by pounding small, internal metal hammers against an anvil.
