GRK Fasteners


Uli Walther started working for German screw maker Reisser Schraubentechnik GmbH in Kuenzelsau, Germany, to manage Reisser's Swiss operation.   




Due to his success in managing the Swiss process, Uli was promoted to General Manager of North American operations. 


GRK Canada Limited was founded in September of 1990 after the Walther family visited four communities in Ontario.   




The bankruptcy of Reisser Schraubentechnik GmbH led the investors, Uli, Gerda, and three others, to take ownership of GRK.
