Calculating tightening torques for screws - What role does resilience play?

This article explains how to calculate tightening torques for screws and threaded joints. Threaded joints are one of the most commonly used connection methods. They are used in a variety of applications in mechanical engineering, such as custom machinery, aerospace, 3D printing, and the medical, pharmaceutical, and automotive industries.

Threaded joints provide a secure and efficient connection between two or more components. The strength of a threaded joint depends, among other things, on the torque exerted on the screw head. It is therefore important to calculate the correct tightening torque to obtain a reliable and secure threaded joint.

Tensile strength classes of stainless steel screws and nuts

The tensile strength of steel and stainless steel is a critical parameter when it comes to the load-bearing capacity and safety of threaded joints. It is made up of two key parameters for steel screws based on which the tensile strength and the yield strength can be easily determined. But starting at a certain size, stainless steel screws and stainless steel nuts are marked with a letter-number combination (e.g. A4-80). The letter-number combination arranged in front of the hyphen assigns the screw so marked to a material group and steel group and thus provides information on the basic material properties of the screw. The number 80 to the right of the hyphen indicates the strength class. This article shows how to use the strength class of stainless steel bolts to determine their limits of use and provide an overview of the load-bearing capacity of typical strength classes.
