Description

Double Pass Brass Universal Adapter Coupling 3mm × 3mm

The Double Pass brass adapter coupling 3mm × 3mm is created for joining two shafts of equal diameter in compact mechanical drive systems. Its rigid brass sleeve allows smooth rotational energy transfer when both shafts share accurate alignment, making it suitable for consistent torque delivery in miniature power modules.

After positioning each shaft into the dedicated bores, tighten the included M3 holding screws to lock the connection. This coupling’s brass body provides excellent resistance to wear and surface oxidation, making it dependable for small robotics, RC propulsion links, and precision prototype assemblies where uniform drive response is necessary.
