Product Description
WING-NUT KIT for Coats brand wheel balancers that have a 28mm Double-Thread (see below) shaft (OEM).
Fits the following models IF THEY HAVE THE ORIGINAL 28MM ( ~1.125") SHAFT: 700, 800, 825, 850, 925, 950, 1000, 1001, 1025, 1050, 1055, 1250.
Many Coats 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 Coats 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 Coats Wheel Balancer with a 28mm shaft and 4mm thread spacing, you have a 28mm X 8mm Double Thread Shaft. This can be confirmed by verifying that there are TWO thread-starts 180 deg. apart at the beginning of the threads.
