Pneumatic Torque Wrenches are compact, accurate, and faster tools with continuous rotation for easily loosening and tightening bolted connection without the effects of damaging hammering mechanisms found in impact wrenches. Torque control is achieved by adjustment of the air pressure. An air pressure versus torque graph and a calibration certificate is supplied with each tool and allows specific torque values to be set. For more critical applications, Pneutorques can be fitted with a torque transducer and the precise torque output displayed. The tool can then be shut off at the desired torque either manually or automatically using suitable control circuitry.
