After the shafts are inserted into each bore, the included M3 clamp screws provide a tight and reliable fit. Because the motor shaft coupling joint resists slip during movement, it is frequently used in miniature robotics, RC prototypes, and instrument adjustments that benefit from consistent alignment and torque stability.

Description
Double Pass Brass Universal Adapter Coupling 2.3mm × 4mm – Motor Shaft Coupling Joint
The motor shaft coupling joint helps connect shafts of different diameters with stable torque transfer, making it suitable for builds that require precision. This design also supports compact assemblies used with coupling pump and motor layouts or lightweight coupling wheel mechanisms. The Double Pass brass adapter coupling 2.3mm × 4mm maintains smooth rotational output due to its rigid cylindrical structure and accurate bore sizing.After the shafts are inserted into each bore, the included M3 clamp screws provide a tight and reliable fit. Because the motor shaft coupling joint resists slip during movement, it is frequently used in miniature robotics, RC prototypes, and instrument adjustments that benefit from consistent alignment and torque stability.
