Dongbu Spline Servo to 1/4" Shaft Coupler (Set Screw)

This servo to shaft coupler is intended to fasten a 1/4" shaft to the output spline of a servo that has a 25 Tooth Dongbu Spline. The coupler fastens to the servo by installing the stock servo screw down through the center of the part prior to inserting a 1/4" shaft into the bore. For a solid connection between the coupler and a shaft, we recommend that you use a 1/4" D-Shaft so that the set-screw is able to tighten down on the flat and reduce any chance of slippage. Patented.
