Important Note

Be sure to never use the same set screw on the shaft twice. There are two set screws in each of the two holes in the stainless steel rotor. One is tightened onto the shaft, and the other is tightened onto the first lock it in place against the shaft. The set screws are made with a cup at the base that compresses into the shaft, ensuring a secure grip.
