Manufacturing specialist for screws and fastening elements
REISSER Schraubentechnik GmbH is a manufacturer of fasteners and connecting elements founded in 1921, with its own production facility in Ingelfingen-Criesbach (Baden-Württemberg). The company, part of the Würth Group since 1994, specializes in the manufacture of stainless steel screws in grades A2, A4, A5 and A8 as well as customer-specific fastening solutions made of steel, bimetal, aluminium, brass and special materials. Production is carried out as cold forming on presses, followed by thread rolling, resistance welding for bimetal screws and solar fasteners, heat treatment up to strength class 8.8/10.9 as well as washer assembly. In the in-house electroplating shop, zinc plating, electroless nickel plating, electropolishing, pickling/passivating and head coating in over 25,000 colour shades are offered – also for customers from the automotive industry, valve technology and mechanical engineering. Key areas of application are timber construction, terraces, building envelope (roof, facade, ventilated curtain wall), solar, industry and window construction. Since 2025, shipping has been handled via the new logistics centre in Osterburken; around 310 employees ensure production and sales.
