Testing of Fasteners

Fasteners such as hooks and eyelets made of metal, as well as screws, nuts, bolts and rivets are used to join components and metal sheets and sections that must not separate under load. Fastener technology in general, particularly welding and associated technologies, also belong to this group. Relevant standards are DIN EN ISO 9015-1 and -2, as well as DIN EN ISO 14271 and DIN ISO 22826.

Testing of screws/bolts and nuts

The majority of fasteners fall under the category of nuts and bolts in seemingly endless variations; they are one of the most important fastening elements and can be found essentially everywhere. They are used in the construction of complex machinery and equipment, as well as vehicles and buildings. Since mechanical stress is concentrated on these types of connection points, the integrity of fasteners is extremely important.

A wide variety of tests apply to screws/bolts and nuts. This includes tensile tests and hardness tests as well as fatigue tests, torsion tests or Charpy impact tests.
