YKK Quality Management
Since the late of 1950, YKK has been building up the worldwide group network and running Good Quality Management System throughout the network. In 1997, we established the Quality Management Committee, called FGQMC (Fastening Global Quality Management Committee) to assure the quality of our products at global level and to satisfy our customer with safety and reliability on our products. FGQMC is responsible for study on world laws and regulation, test and monitor the quality level of the products, unification of product specification and other activities to assure product quality to our global business partners.
