M5 Propeller Prop Nut Cap CW CCW for Emax 2204 Brushless DC Motor

This M5 Propeller Prop Nut Cap CW CCW for Emax 2204 Brushless DC Motor is the set of two different i.e CW and CCW Nut Cap for 2204 brushless motor to be fitted above the propeller.

Prop nuts of different directions usually come in different colors, such as black and silver for better user-friendliness.

Some mini quad motors are labeled CW and CCW, and it can cause a hell of confusion for a lot of people in this hobby including experienced quadcopter builders.

Basically, CW (clockwise) and CCW (counterclockwise) motors are still the same motors, apart from the prop shaft threads which have opposite direction. That means for a CCW motor, the prop nut is secured by turning clockwise. And for CW motors, the prop nuts need to be rotated anti-clockwise in order to fasten.

Advantages of having different CW and CCW threads

So why have 2 different shaft threads and making it so confusing?

They call this ‘Self-locking’ because on a quadcopter we have 2 motors spinning clockwise direction and the other two spinning counter clockwise. By using threads that are the opposite to motor spin direction, the prop nuts automatically lock themselves down and won’t come loose.

However, it becomes difficult to source spare prop nuts for both threads. And it also makes it confusing to which way we should turn to remove the prop nuts when changing propellers.

Prop nuts are basically M6 nylon nuts. In hardware stores, they are referred to as right handed and left handed thread as opposed to CW and CCW.

Identify CW and CCW Threads

So basically if you can fasten the prop nut clockwise, then you have a CCW motor, for which you should get the Right handed thread nut (standard thread).

For CW motors, go for the Left-hand thread nuts (reverse thread)
