Torque Wrench Limitations: Accuracy and Range

A Torque Wrench is a vital tool used to apply the necessary torque when tightening bolts and nuts. It finds applications in the automotive, aerospace, engineering, and construction industries.

This tool has been in the market for over a century. But it has seen considerable improvements over the decades, thanks to technology.

When using a torque wrench, you always want to achieve consistent accuracy while avoiding overtightening or under-tightening situations. Selecting the right torque wrench for your applications and sticking to the torquing best practices are critical to achieving the desired outcomes.

Pneumatic torque wrenches and proper bridge bolt load

For many years the tightening and torquing of bridge bolts traditionally have been done with impact guns being checked on a Skidmore/Calibore bolt load testing device for verification.   While this has always been acceptable in the past, many engineering and inspection firms are now requiring calibrated shut off tools to be used in place of impact guns. The Skidmore/Calibore used in conjunction with an impact gun verifies that that tool has the capacity to go to the required bolt load. The issue with this method, is that it’s operator dependent on the time the tool operator continues to hold down the trigger on the impact. There is no shut off when the correct bolt load is achieved. Therefore, the tool operator could over or under apply the proper bolt load required.
