Ever since its founding, quality has been central to the YKK Group’s management, and all of its business activities revolve around the assurance of quality. Maintaining stable and constant quality has become one of the key concerns for many of the global manufacturers, and in order to support these companies, YKK has established YFS – YKK Fastening Standards – to provide products of the same quality level, wherever and whenever they are manufactured. Each YKK production site conducts various quality tests and reports the results to Japan HQ on a regular basis in order to maintain and assure a consistent quality level.
