ITH customer focus is a company guideline

To have several locations in the US refers to the quality and fundamental company guideline “ITH Customer Focus”, which means that all efforts are 100 % geared to customers’ demands. “We congratulate ITH USA on this accreditation and appreciate all efforts that went into it”, says Frank Hohmann, who leads ITH Bolting Technology in Germany together with his brother Jörg Hohmann.  

Back in 1995 Frank Hohmann had worked on the first quality management handbook for the ITH headquarters in Germany, which reflects the importance of quality in all ITH business procedures. “We have been the first company in the market, which was certified at that time”, Frank Hohmann explains. “We can say we are a pioneer in quality management. And this commitment to quality will persist”.
