In order to ensure this resistance adequately, friction and the self-releasing behaviour must be measurable and adjustable. Screws and nuts are used to join and fasten these components to each other in such a manner that they are releasable to carry out repairs or to replace parts.This is the point when friction comes into play.

The clamping force to be applied, which is necessary to fasten a screw connection between components securely, is therefore of great importance for practical purposes.

It is also important they do not unintentionally release at very different temperatures such as in summer or winter.The screw manufacturer must produce the friction properties during the production process and demonstrate them to the customer.

It is understood as a permanently present, internal release torque of the screw connection. In the end, the screw supplier and the screw user are both responsible to their customers – a crucial reason for all of these groups to carry out the verification of friction coefficients.

With a wide range of friction testing machines and multi-component sensors for the determination of friction coefficients TesT GmbH, located in Erkrath, Germany, provides complete solutions for screw and bolt testing.
