STOCKOs 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.
