Dörken MKS offers platform for critical dialogue


The new MBN 10544 standard is currently a sensitive and much-discussed topic in the automobile sector. This is due to the fact that current Daimler specifications require screws and bolts to be tested against steel, although in practice the situation is different: the majority of fasteners are screwed to aluminium or KTL. This situation has moved Daimler to develop a new standard – MBN 10544. The result is significantly more demanding testing requirements for coaters and manufacturers of fasteners and chemicals. Fasteners should be applied a total of five times to three surfaces – aluminium, KTL and steel – and for five threaded fasteners the thread, head and overall friction should lie within a prescribed tolerance band. In addition to additional time requirements, there is also a financial impact from this.

At the end of April Dr. Akramullah Aminy of the small parts optimization (KTO) team at Daimler explained the new requirements of the standard at a workshop organised by Dörken MKS. Under the aegis of the CORROSION COLLEGE, some 100 participants took up the invitation of the corrosion experts.

Here they were able to experience a diverse and hotly-debated workshop, at which they not only had the opportunity to discuss with a Daimler representative, but also a representative of the Deutscher Schraubenverband fastener association, Andrea Eberhard. Thanks to Dörken MKS expert Michael Stähler there was also a refreshing of the basics of coefficients of friction and the development of specifications in the car sector, as well as experience gained in the practical application of the new standard.

In conclusion there was an animated discussion led by Dr. Stefan Beyer, Managing Director of the Deutscher Schraubenverband. During this session Dr. Aminy responded to the critical questions and observations of the participants, which also led to an avid interaction

Overall, the workshop was received very well by all those involved. The opportunity to enter into dialogue with one another and discuss the consequences of the standard was viewed particularly positively. “The highly mixed group of participants meant that there were many interesting contributions to the discussion,” summed up one of the participants.
