Innovation and tradition

Today, FASTENRATH Befestigungstechnik GmbH is one of the world’s leading manufacturers of machine screw nuts and cold-forged parts. It employs a total workforce of 200 people at two locations. The figures speak for themselves: 6 million parts produced each day for more than 850 customers worldwide. The company did not achieve its present size overnight: it grew over the course of decades. Today’s success is based on mature experience, continuous innovation and reliable quality.

1909 – With the establishment of FASTENRATH, Ernst E. Fastenrath (14 July 1886) founds a new company and a long tradition. The trained metalworker first organises the production of square nuts and then expands production to hexagon nuts after a few years. The founder’s innovative spirit and business acumen is already apparent.

1924 – A new process for turned nuts leads to a boom in sales from 1931 to 1934. It provides the impulse for the purchase of the five-storey production building on Herscheider Street in Plettenberg.

1934 – FASTENRATH celebrates its 25th anniversary. The pickling, rolling, and wire drawing facilities move to a subsidiary plant together with the wire rope warehouse. The 50 employees can reach it from the main plant by rail.

1941 – World War II affects the company. As protection against bombs along the Plettenberg-Herscheid rail line, the subsidiary plant in Westerburg is built and the production facilities are relocated.

1949 – FASTENRATH develops the first of its own machines for the production of cold-forged nuts. This marks the birth of ERFA nuts.

1955 to 1957 – The company flourishes and builds a new hall in Plettenberg. An additional 3,500 m² of production area in Westerburg and the addition of the office building in Plettenberg testify to the company’s success.

1959 – The success story continues. FASTENRATH now has 400 employees and an annual turnover of over 7 million German marks.

1975 – The range of products and services expands. FASTENRATH now also offers the development, manufacture and marketing of cold-forged parts.

1997 – Quality management is placed centre stage. Certification according to DIN ISO 9001 and the DIN ISO 14001 environmental system are the best proof of this.

1999 – Construction of the new high-bay warehouse in Plettenberg with around 3500 storage bays. The loading of lorries in Herscheider Street is a thing of the past, now “just-in-time” deliveries are possible.

2002 – Werkzeugbau Westerburg is equipped with state-of-the-art technology. That includes, among other things, a sinker EDM machine, a wire cutting machine, and a CNC hard turning unit.



2003 – In Plettenberg, a fully automated packaging line increases the daily production capacity and improves working conditions. Westerburg obtains the first six-step cold-forming press.

2007 – Modernisation of the subsidiary plant in Westerburg continues. Another storey is added to the office building and a 2000 m² production hall is built.

2008 – A new cold-forming press with 650 tonnes of compressive force is installed in the new production hall in Westerberg.

2009 – On its 100th anniversary, FASTENRATH employs 185 people, ships 12,000 tonnes of product per year, and has an annual turnover of 45 million euros.

2011 – The production and storage areas in Westerburg are expanded by 2,000 m.

2012 – Another 700-tonne press goes into operation in Westerburg.

2014 – The main administration building in Plettenberg is completely renovated.

2015 – FASTENRATH acquires additional industrial land for future expansion options in Plettenberg. The course is set for continuous growth. Innovations will continue to shape the future.

Today – FASTENRATH Befestigungstechnik GmbH is one of the world’s leading manufacturers of machine screw nuts and cold-forged parts. The figures speak for themselves: every day 200 employees at two locations produce six million parts for more than 850 customers worldwide.
