Description
Double Pass Brass Universal Adapter Coupling 3.17mm × 4mm
The Double Pass brass adapter coupling 3.17mm × 4mm is engineered to connect shafts of slightly different diameters while maintaining stable rotational torque flow. Its rigid brass sleeve construction delivers smooth drive continuity in compact transmission systems where proper shaft alignment is already achieved.Position each shaft into the dedicated bore and tighten the supplied M3 clamping screws to lock them securely. This firm grip minimizes rotational slip and helps maintain dependable performance in model propulsion drives, lightweight robotics, and prototype motion assemblies.
