A pneumatic screwdriver is a tool that is powered by compressed air. The pneumatic screwdriver allows a user to place a lot of screws and never requires recharging like battery-powered screwdrivers. These features make this screwdriver suitable for assembly lines. Maintenance of pneumatic screwdriver is so easy and just involves a light application of oil in the air connection. This is to lubricate the motor as the air flows through. In assembly lines if the worker use a hand-held and powered screwdriver it results in falling behind the schedule and also severe injury to the workers' wrists and forearms.
