Torque is a measure of force that can be applied to rotate an object. It is measured in units of Newton meters or pounds-feet. Torque on bolts is the measure to ensure the bolts are not overtightened for durability and future reuse. This article discusses various methods on how to measure torque on a bolt.
Method 1: Using a Torque Wrench
If you use the correct torque wrench, you can use this method with no complications. The advantages of this method include calculating the actual torque applied with precision and ease. It is also accurate in low-torque situations.
Method 2: Using A Caliper or Micrometer to Measure Diameter Change on a Threaded Bolt
When measuring the torque of a threaded bolt, a caliper or micrometer can be used to measure the diameter. A micrometer is typically more accurate than a caliper and is used most often in this case. If a caliper is used, the diameter can be measured by the thickness of the jaws of the bolt.
Method 3: Use of a Digital Wrench
The digital wrench can easily detect the torque and provide an accurate reading. It is sturdy enough to be used on different materials, like steel and aluminum. This method on how to measure torque on a bolt is very precise and has low error levels. When measuring torque using a digital wrench, three steps are to follow. One, determine the level of tightening of the bolt. From there, measure the distance between where you started and where you are. Finally, using the digital wrench, convert this distance into pound-force.
