Screws/special screws from OEB – quality at favourable market prices from the manufacturer and supplier

Otto Eichhoff GmbH & Co. KG (OEB) has been manufacturing screws for 100 years. In the course of market globalisation we have been purchasing products on the world market for some years because this is cheaper. But we are still manufacturing special screws which demand great manufacturer know-how. Our know-how enables us to offer our customers the required quality at favourable market prices – regardless of whether we produce ourselves or purchase elsewhere.
