The AA 40mm Quick Nut and Clamping Cup are designed for durability and speed, eliminating the wear from dragging the sharp nut teeth across the threaded balancer shaft.

Note: The Hunter wheel balancer double thread quick take-up design is the best in the market and is challenging to match. A typical thread starts at only one spot on the shaft, and double threads start at two places 180 deg. from each other. The wingnut for these double thread shafts has 8mm thread spacing, and the shaft has 4mm spacing, but it is two sets of 8mm spaced threads 180 degrees out of phase. This allows the wing nut to start threading in 2 possible positions instead of just one.

Thread spacing is the distance between one thread and one space; for example, the distance from the left edge of a thread to the left edge of the following thread. If you have a Hunter Wheel Balancer with a 40mm shaft and 4mm thread spacing, you have a 40mm X 8mm Double Thread Shaft. For Coats models, confirm 4mm spacing AND follow the model applications as listed.
