Screws, nuts, fittings or springs - everyone of us has already used these small parts. They can be found everywhere, and yet we rarely think about the constantly high loads to which these components are subjected. Failure can result in exorbitant costs or, even worse, danger to human life. For this reason, ever higher quality requirements are being placed on all types of fasteners.
To ensure that these tiny elements cause no major disturbances, potential material defects such as surface cracks or pores must be detected in time. Only then can countermeasures in the production process be undertaken and defective parts promptly rejected.
