Founded on November 8, 1901

The STOCKO success story began on November 8, 1901 in Sonnborn, which today belongs to Wuppertal. The newly founded company Stock & Co. launched a real innovation on the market with its very first product, the sew-on press stud. 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 in the market.

STOCKO has 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 Closure Technology division, YKK STOCKO FASTENERS GmbH is integrated into a worldwide sales network.

“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.”
