Knowing that there are very few articles explaining the benefits of bolt tensioners, this article will explore on what benefits customers gain from bolting with a stud tensioner. First, we will explain the operation of a bolt tensioner and then move to the benefits it offers.

As bolts in major industrial applications tend to loosen due to impact from constant vibrations and load, bolt tensioners and torque wrenches are frequently used during shutdown to tighten them and maintain joint-integrity. However, it is an extremely tedious and time consuming process considering the fact that multiple bolts need to be torqued or tensioned with limited tensioners and torque wrench. In this article, we will explain how measuring bolt elongation with an ultrasonic bolt measurement device like the TensionPro Sonar can confirm if retightening of bolts is required.
