Etti 4mm to 3/16"(4.75mm) prop adapter. This is used if you are trying to adapt a 3/16"(4.75mm) propeller to a 4mm threaded shaft. How this works... The threaded drive dog is first threaded onto your 4mm threaded shaft. Slide your propeller onto your shaft. Then install and tighten the included adapter/propeller nut. Keep in mind, you need enough threads on your shaft to fit the prop hub you are trying to adapt. Includes: (1)Drive Dog (1) 3/16"(4.75mm) adapter/propeller nut Fits:M4 threaded shafts
