Torque analysis - Higher process reliability thanks to screw joint tests

Increase process reliability thanks to a detailed examination of your application. A torque analysis is used to determine reliable tightening torques and can be carried out either in one of our laboratories or at your location.

Why is a torque analysis necessary?

Thread-forming screws are frequently used in the construction of machinery. However, since the various materials, screw types, screw-in depths, hole geometries and other parameters do not provide universal information on torques, torque analyses are indispensable for reliable screw connections. In Bossard’s application engineering department, torque analyses are part of our day-to-day business. Torques in the range of 0.1 - 1500 Nm can be measured and recorded at the bolting test stations. If required, Bossard also has accredited laboratories in each world region with corresponding testing competencies for recognized validation.

 

How is a torque analysis performed?

Whenever possible, torque analyses are carried out on the customer’s original components. During the test, the connections are tightened until they fail. As a result, the components are destroyed after the test and can no longer be used.

 

How is the data evaluated?

After the test, the recorded torque and angle of rotation curves are evaluated by our application engineers. Both the screw-in torque and overtightening torque are determined. The resulting torque and angle of rotation curves can then be used to draw meaningful conclusions about the behavior and failure of the connections.

 

What is the goal of a torque analysis and what are the benefits for the customer?

Several factors must coincide before a connection can be considered reliable. For example, the overtightening torque at which the connection fails must be significantly greater than the screw-in torque that is required for thread forming. Only then can the recommended tightening torque be reliably defined and you, as the customer, can be certain that the connection can be properly tightened, thereby minimizing your component’s risk of failure.
