A Mountz Loading Bench provides engineers and metrology professionals with a precision, laboratory-grade solution for effortless and accurate torque wrench calibration and presetting. Designed to simplify calibration processes, these loading benches deliver consistent, repeatable results across torque ranges up to 2500 lbf.ft. Torque wrenches require regular calibration to maintain accuracy and avoid errors in assembly processes. The Mount Loading Bench enables faster operator calibration by minimizing user-induced errors and transducer misalignment, ensuring reliable torque application every time.

Torque Sensor Set-up Attach the BMX to the the rotating baseplate usin Attach the BMX to the the rotating baseplate using the correct hardware provided. Make sure the wrench is within the torque range of the BMX model. If the tool is under the torque range, then the accuracy may not be reliable. If the tool is over the torque range, then you may overtorque the BMX and damage the sensor.
