Servo to Shaft Coupler (H25T Spline, 1/4" Bore)
£7.26
This coupler allows you to drive a 1/4" round shaft or 1/4" D-shaft with a 25 tooth spline servo.
Details
The screw that holds the coupler onto the servo needs to be installed first, followed by the 1/4" shaft to be driven.
The M5 set-screw can then be tightened down with a 2.5mm hex driver for a tight hold on the shaft.
