M5 CW CCW Propeller Fixed Adapter Nut Cap For Brushless DC Motor

The two distinct nut caps, CW and CCW, that are to be installed above the propeller are part of the M5 CW CCW Propeller Fixed Adapter Nut Cap For Brushless DC Motor set.

Prop nuts with varying orientations typically come in various colors, including silver and black, to make them more user-friendly.

There are small quad motors with labels that read CW and CCW, which can be very confusing for many enthusiasts, even professional quadcopter builders.

The only real difference between CW (clockwise) and CCW (counterclockwise) motors is the direction of the prop shaft threads, which are different. In other words, a CCW motor’s prop nut is fastened by rotating in a clockwise direction. Additionally, in order to secure the prop bolts on CW motors, they must be turned counterclockwise.

The benefits of distinct CW and CCW threads
Why then are there two distinct shaft threads why is everything so confusing?
Because two of a quadcopter’s motors rotate clockwise and the other two spin counterclockwise, this phenomenon is known as “self-locking.” By using threads that are in the opposite direction as the motor spin, the prop nuts self-lock, preventing them from coming free.
Nevertheless, finding extra prop nuts for both threads becomes challenging. Additionally, it becomes unclear which way to turn when changing propellers in order to release the prop nuts.
In essence, prop nuts are M5 nylon nuts. Rather than CW and CCW, they are called right-handed and left-handed threads at hardware stores.

Determine the CCW and CW Threads
In other words, if the prop nut can be tightened in a clockwise direction, your motor is CCW, and you need to purchase a right-handed thread nut (standard thread).
Choose left-hand thread nuts (reverse thread) for CW motors.

Note: There is no motor included in the kit.
