Clutch nut BGM PRO M12 x 1.50 collar Ø=18.6mm h=9mm WS=15

Thus suitable for all vehicles from the 1950 model year, such as V1–V5, VNB, VNA, GS150, GS160, Sprint, Rally, GT, GTR, T5, Cosa1, PX, PE etc...

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 its precise manufacture, it is also suitable for a tightening torque of over 70 Nm due to the use of grade 10 steel (in our internal tests, we were able to load the nut with a tightening torque of 170 Nm). Conventional castle nuts often give up at 40 Nm. With the BGM nut, slipping and damage to the crankshaft or clutch hub caused by a loosened clutch nut are a thing of the past.
