The only way to properly determine the optimum tightening torque for a given application is to simulate the exact application. This should be done with a tension indicating device of some type on the bolt in the application. The bolt is tightened until the desired P (load) is indicated by ...
The advent of ultrasonic measurement systems and hydraulic torque wrenches has made it possible for the U.S. Bureau of Mines to perform torque-tension measurements in the laboratory and the field much more accurately. The results indicate that the amount of initial bolt preload may be ...
When applied torque and the resulting tension (preload) in the bolt are measured during tightening and plotted on a graph, there is a linear relationship between the torque and the tension. The bolt tension is directly dependent, and proportional to, the applied torque. This is illustrated by ...
SeeTorque Force Design Equationswebpage and torque chart page for recommended fastener torque and equation data. This calculator uses a practical starting point for all threaded fastener tightening analysis and uses the basic elastic torque-tension equation. ...
What is bolt torque? Torque is a measure of the conversion of linear force to rotational force at some distance from the axis of rotation. When applied to a bolt, this force becomes tension in the bolt threads, which in turn applies a clamping force (or load) between the two materials ...
