Extended Hexagon Coupling 30mm Length for Motor Shaft Coupling 30mm:5mm Removable Side Panels with easyThe extended hexagonal coupling can extend the transmission shaft, and the motor with the coupling can effectively extend the transmission distance. This coupling is often used to connect the reduction motor shaft and the hexagonal wheel, and can also be used to connect the motor shaft and other model accessories. Specification: Material: Brass plating anti rust, high hardness, anti corrosion Color: Gold Inner Diameter: 3mm, 4mm, 5mm Diagonal
