Description
Double Pass Brass Universal Adapter Coupling 3mm × 4mm
The Double Pass brass adapter coupling 3mm × 4mm is built to connect two shafts of slightly different diameters while maintaining stable rotational movement. Its rigid brass sleeve efficiently transfers torque when both shafts are positioned with proper alignment, making it suitable for compact mechanical drive layouts.Simply insert each shaft into the appropriate bore and tighten the included M3 securing screws. These screws provide a firm bite on the shaft surface, reducing rotational slip. The brass housing offers steady performance in micro robotics, RC propulsion assemblies, and lightweight gear-driven prototypes where durability matters.
