Mechanical properties for fasteners

Being aware of the mechanical properties of a fastener, e.g. its tensile strength and the forces to which the joint will be subjected, is essential in being able to select the right fastener.
One fundamental requirement is that the fastener must not break or experience lasting deformations as a result of the loads it will normally experience during its anticipated service life.
The nature of the loads and the fastener’s material properties can, along with the design and the surrounding environment, give rise to various forms of damage. In order to select a fastener with mechanical properties that provide a sufficient safety margin, you need to know which criteria could influence the potential damage mechanism.

In our test laboratory, we ensure that the mechanical properties of our fasteners, e.g. tensile strength, hardness and impact strength, correspond to the requirements laid down by authorities and our customers.

The following link specifies the mechanical properties of the various types of fastener.
