Idea and development
The idea for the new counter nut originates from Malte Fürstenberg from Fürstenberg Fittings in Hamburg. Malte was developing a new surfboard, but the typical hexagon nuts he was using were protruding from the surfboard and because of this disturbing the hydro-dynamic flow and creating turbulence. The question thus arose: What would a nut look like that is countersunk into the material and is safe and strong at the same time?
Where does the Name ‘CONU‘ come from?
CONU is a modified form of the Latin conus (‘the cone’) and is also an abbreviation for COUNTER NUT.
