Our history

The traditions of Bumax go back as far as the middle of the 17th century when a forge was established in Åshammar, Sweden and a foundry in Svartå.

Åshammar Bolt Factory was founded in 1899, and in 1926 was one of the very first companies in the world to produce austenitic stainless steel fasteners. Gradually the company changed its products and became a true expert in developing and manufacturing cold headed stainless steel fasteners. Today we make fasteners from a wide range of stainless steel materials and our products are used around the world in the most demanding applications.

In 1997, the Bumax brand was registered. The name carries the tradition, the history and the knowledge of generations of engineers and bolt makers in Åshammar and is known as the strongest stainless steel bolt in the World.
