This Haweka quick wing nut set will fit all model balancers with 28mm X 3mm shaft. To check, measure the shaft diameter (28mm) and the thread spacing (3mm) on your balancer shaft. Thread spacing is the distance of one thread and one space; for example, the distance from the left edge of a thread to the left edge of the next thread.
NOTE: YOU MUST CHECK THE SHAFT THREAD PITCH ON YOUR 28mm SHAFT TO SEE IF YOU HAVE A 3mm, or 8mm BEFORE ORDERING. THIS FITS 28mm X 3mm SHAFTS ONLY!
