YINETTECH 4PCS Bicycle Crank Arm Bolts E-Bike M15 ISIS Crank Screws Compatible with Bosch E-Bike Drives Compatible with Brose E-Bike Drives

Surprised that my E-Bike crank nut had worked loose and fell out while out a long way from home causing my left crank arm and pedal to fall off ! It turns out Bosch Performance CX crank bolt sockets are not a left hand thread to prevent bolt loosening. I have used two of these to replace my right side bolt and the other to replace the lost bolt. I used removable thread locker on the bolts to stop them coming loose again. There is no indication on torque setting so I set it at the same as a wheel bolt of 12Nm. So far all working great and has solved a major problem trying to get original bolts which for some reason were not available. These got me riding again. I was going to use them as a temporary solution until I could obtain the originals but as they are still unavailable I now am leaving them installed as a permanent replacement. I carry the 2 extra boots with me in case of loss again but with the thread locker all tight and working perfectly. The price is excellent too. Definitely recommend.
