4007 Series Hyper Coupler (6mm D-Bore to 6mm D-Bore)

This 6mm D-Bore to 6mm D-Bore Hyper Coupler is a strong, compact, balanced way to couple two shafts together.  As with all ‘Hyper’ parts, this too is balanced so you can spin it up without concern of creating unwanted vibrations through your drivetrain.
