Selected User Reviews For BQLZR Blue 6mm to 6mm Aluminum Shaft Coupling Rigid Coupling Coupler Motor Connector with Spanner Pack of 2

It's a good idea to have an M4 tap on hand

3/5

I had the same problem as one of the other reviewers: One of the couplers didn't have all of its holes tapped. It only took a few minutes to make it usable with an M4 tap, but I kind of expect something like this to come fully machined and ready to use when I buy it.

Connector for the motor shaft

5/5

This is fantastic. 6mm shaft connector with a length of 25 inches. Before purchasing a selector, use a digital caliper to measure your motor shaft. 6mm=. 25in.

One of the two couplers was defective, and I couldn't get any of the set screws far enough into the inner diameter before they became entangled and stuck

3/5

The second coupler worked perfectly, and I believe the holes on the defective coupler were not fully tapped.
