Research and development

YKK STOCKO works with the customers to develop customer-specific fastener systems, which are constantly being optimised and adapted to new requirements. The development centres are part of a global network and are therefore able to access the latest technologies. This guarantees a rapid period of development.

Foundation on 8th November 1901

STOCKO’s success story began on 8th November 1901 in Sonnborn, which is now part of Wuppertal. With its very first product, the sew-on press stud, the newly founded company Stock & Co. brought a real novelty onto the market. Over the years, the brand name STOCKO developed from the original company name. It became the company name in 1923 due to its high acceptance and profile on the market.

STOCKO has developed from a small production company to an internationally active company, which has been part of the globally operating YKK Group since 1994. In the field of fastening technology, YKK STOCKO FASTENERS GmbH is part of a global sales network.

Member of the YKK Group

As a globally active group of companies focusing on fastening and architectural products, the YKK GROUP is present in 71 countries with 114 companies and employs more than 44,000 people.

The YKK product range includes technical and stylish solutions for plastic and metal fastener systems. These include press studs, rivets and decorative elements, as well as hook and loop fasteners and textile and plastic products (TFM). The YKK Group is also the largest developer and manufacturer of zips in the world. YKK plays a role wherever something is closed, fastened or secured.

In addition to fastening technology, another field of activity of the YKK Group is architectural products (AP). With doors, windows and building façades, YKK AP creates lasting values for the future and contributes, as a company, to the creation of comfortable living environments and urban spaces.

„IN A FOREST, SOME TREES ARE OLD AND VENERABLE, RICH IN EXPERIENCE AND KNOWLEDGE. AND SOME TREES ARE YOUNG, SCARCELY MORE THAN SAPLINGS. SOME TREES ARE TALL, OTHERS ARE SHORT. BUT EACH TREE GROWS ONWARDS AND UPWARDS IN ITS OWN UNIQUE WAY. AN ORGANISATION IS LIKE A FOREST, FULL OF POWER AND VITALITY, WHICH MAY CONTRIBUTE TO SOCIETY.“
TADAO YOSHIDA, FOUNDER OF YKK
