40MM Shaft Manual Hub Wing Nut
Got exactly what I needed. Steve helped me find the right part for my application. Thanks so much!

Many Hunter wheel balancers have a "double thread quick take up" thread design that is difficult to match. A normal thread starts at only one spot on the shaft. Double threads start at 2 spots 180 deg. from each other. The wingnut for Hunter double thread shafts has 8mm thread spacing and the shaft has 4mm spacing but it is actually 2 sets of 8mm spaced threads 180 degrees out of phase. This allows the the wing nut to start threading in 2 possible positions instead of just one.
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. If you have a Hunter Wheel Balancer with a 40mm shaft and 4mm thread spacing, you have a 40mm X 8mm Double Thread Shaft.
Your choice of just the wing nut or the full set with pressure cup and protective rubber ring.
Compatibility depends on the balancer's shaft and clamping configuration. Verify the shaft diameter, thread form and number of starts, and the required pressure cup and ring before ordering.
