We have our roots in Åshammar Forging & Nail foundry, which was founded in 1660. The Åshammar Bolt Factory was established in 1899, and in 1926 we were one of the very first companies in the world to produce austenitic stainless steel fasteners.
Our products have developed over time and we have become a world-leading developer and manufacturer of stainless steel fasteners. In 1997, the BUMAX brand was registered and the name carries with it the proud tradition and expertise of many generations of engineers and bolt makers in Åshammar.
Today, BUMAX is known as the strongest stainless steel bolt in the world, with fasteners manufactured from a wide range of stainless steel materials for use in the most demanding applications.
