A solid brass coupling for connecting 6mm shafts to 6mm shafts. Applications include connecting motor to drive shafts in CNC and model making applications. Reducing couplings are part bored from each end, non-reducing couplings are smooth bore all the way through. Each coupling is supplied complete with two M3 grub screws to grip each shaft. Two additional tapped holes are provided at 180 degrees opposite where additional grub screw (not included) fixing security is required. Additional grubs are available here.

We can custom bore out to 1/4" or 8mm as a special. If you only require one side boring out to form a reducing coupling, please tell us in the notes section when you check out. If you select the 6mm option, we will ream the coupling to check accuracy but this is not really necessary as we find them to be okay without it.
