Nylock Nuts, M12x1.25

Nylon lock nuts provide much more resistance to loosening from motor vibrations and axle wiggle caused form regenerative braking than regular nuts or nuts with split lock washers.   

Our M12x1.25 nylocs are made of stainless steel and work with the majority of chinese hub motors with 12mm axles. For motors from Grin this includes the eZee front motors, the G60/G62 bafang motors, and the Shengyi SX1/SX2 motors. 

Just be aware that coarser pitch M12x1.5 and M12x1.75 thread standards also exist and are occasionally used by motor manucturers.
