Worked out . Great selection. Just insure you know the appropriate size of what you need.

I built my own motorized mount using stepper motors and 3D printing. Most steppers sold here don’t included the shaft key so I’m glad this set exists. It worked well for my application.

I use these all the time when working on Boat Lift motors (ShoreMaster & Lift Boss). The kit is awesome to have and ensures you will have the perfect sized key.
