Nutrunner Calibration Service
A pneumatic torque wrench (known as a pneumatic torque multiplier, or pneumatic nut runner) is used when the tightening of nuts and bolts is critical.
An air-operated pneumatic torque multiplier can quickly achieve high torque, particularly essential when time is a factor in securing nuts and bolts. Pneumatic torque multipliers are particularly useful when the same amount of torque needs to be applied to a set number of items, consistently across one structure or on a production line.
Pneumatic torque wrenches are so efficient as they are powered by compressed air, driven by a gearbox that allows the user to control the exact amount of torque applied to a nut or bolt. They traditionally have a very low vibration level as a reaction device absorbs the higher force. The precise torque control allows for the same actions to be repeated across multiple items, whether fastening or unfastening a nut or bolt.
