We recommend using the M5 steel mounting screw to mount IG52 motors. We use these in our Custom Length IG52 DB Robot platform when we mount the motor to the chassis through two 1/8" thick plates.
The M4 Steel Mounting Screws (8mm Length) can be used to mount IG42 motors. We use them in our IG42 SB platform.
This is a set containing a 4 Inch Omni Wheel and a 6mm Nexus Robot Aluminum Wheel Hub. It is intended for use with our Triangular Omni Wheel Robot. The aluminum hub couples directly to the 6mm IG32 motor shaft.
This is a MLT-JR tracked programmable robot platform and is equipped with 32mm motors, motor controller, and Arduino. This Arduino robot can be programmed to be a autonomous robot.
