This nut, made in Germany for us, completely replaces the old-fashioned castle nut and thus allows safe and precise work even with a torque wrench. In addition to the precise manufacturing, it is also suitable for a tightening torque of over 70Nm due to the use of a steel of hardness 10 (in our internal tests we were able to load the nut with 170Nm tightening torque). Conventional castle nuts often give up at 40Nm. With the BGM nut is a slipping and a defect of the crankshaft / clutch hub by a loosened clutch nut ad acta put.
