This servo to shaft coupler is intended to fasten a 1/4" shaft to the output spline of a servo that has a 24 Tooth (C1) 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 slippage. For round profile shafts we do offer a similar coupler that clamps around the shaft rather than using a set-screw. Patented.
