Founded on November 8, 1901

The STOCKO success story began on November 8, 1901 in Sonnborn, which today belongs to Wuppertal. With its very first product, the sew-on press stud, the newly founded company Stock & Co launched a genuine innovation on the market. Over the years, the original company name developed into the brand name STOCKO. It became the company name in 1923 due to its high level of acceptance and recognition on the market.

STOCKO developed from a small production company into an internationally active company that has been part of the globally active YKK Group since 1994.
Within the fastening technology division, YKK STOCKO FASTENERS GmbH is integrated into a worldwide sales network.

Member of the YKK Group

As a globally active group of companies for fasteners and construction products, the YKK GROUP is represented by 114 companies in 71 countries and employs more than 44,000 people.

The YKK range includes technical and fashionable solutions for Fastening Systems made of metal and plastic. In addition to Snaps, Posts and decorative elements, this also includes adhesive fasteners as well as textile and plastic products (TFM). The YKK GROUP is also the world’s largest developer and manufacturer of zippers. Wherever something is closed, fastened or held together, YKK is involved.

In addition to fastening technology, architectural products (AP) form another YKK business division. With doors and windows as well as building facades, YKK AP creates lasting values for the future and as a company contributes to the creation of comfortable living spaces and urban areas.

“In a forest there are old and venerable trees, full of experience and knowledge. Other trees are young and little more than saplings. Some trees are tall, others short. But each tree grows in height and girth in its own individual way. An organization is like a forest, full of strength and vitality, which can contribute to the benefit of society.”

Tadao Yoshida, founder of YKK
