Treskruer

Treskruer is a Swedish engineering company that designs and manufactures fastening solutions for a variety of industrial sectors. Established in 2005 in Stockholm by mechanical engineer Ingvar Johansson, the firm has evolved from a small workshop into a global supplier of high‑performance screws and related hardware. The name “Treskruer” combines the Swedish word for “three” (tres) with “screw” (kruer), reflecting the company’s early focus on triple‑driver systems that simplify installation and maintenance.

The company’s product range includes metric and unified screw families, self‑drilling fasteners, and a line of biodegradable screws produced with plant‑based polymers. In recent years, Treskruer has expanded into composite fasteners designed for use in aerospace and automotive applications. Its products are characterised by high tensile strength, corrosion resistance, and reduced environmental impact, and they are sold to major construction, automotive, furniture, and electronics manufacturers worldwide.

Treskruer operates a research and development division in Stockholm that collaborates with universities to develop new materials and manufacturing processes. The firm has invested in additive manufacturing to produce customized fasteners on demand and has launched an online configurator that allows customers to design screws to exact specifications. In 2019, Treskruer received the Swedish Green Innovation Award for its biodegradable screw technology. The company is listed on the Stockholm Stock Exchange, with a market capitalisation that reflects its position as a niche leader in sustainable fastener technology. Its corporate headquarters remain in Stockholm, while production facilities are located in Sweden, Germany, and the United States.
