    Tips: What is a pneumatic screwdriver?

    A pneumatic screwdriver is a pneumatic tool used to tighten or loosen screws and nuts, etc. A pneumatic screwdriver is compressed air as a power to work. Some are equipped with a device to adjust and limit the torque, called a fully automatic adjustable torque type. Some pneumatic screwdrivers just use the switch knob to adjust the size of the air intake to control the speed or torque, called semi-automatic non-adjustable torque type.
