These parts are for mounting MG-6-48 or MG-6-120 DC gear motors to a robot chassis such as the ROBOT-CHASSIS-3 or ROBOT-CHASSIS-4.
Each assembly pack is for mounting a single motor. Make sure you order one for each motor you need to mount.
Mounting Example The picture below shows how these parts are used to mount a motor to a chassis. The long screws go through the motor and the metal plate and are secured with the locknuts. The smaller screws go through the chassis and into the edge of the metal plate.
