Universal Joint Coupling Metal Shaft Coupling Motor Connector (0.5in×0.9in×2in)

Works great

The ID is 12mm, (0.47in). When I asked to exchange it I was told by the manufacturer it was too expensive to send back and ask if I would accept a discount to keep it. I agreed because I had the tooling and set up to ream a blind hole and make it 0.5in. But beware I don't believe the manufacturer has 0.5in ID universal joints. And no I didn't want to turn the end of the shaft down.

I needed this for the snow shoot handle mechanism. I couldn’t find anything that worked locally. It took awhile to get here. It actually arrived the day after our big snowstorm. But I put it on, made a few adjustments on the handle rod and it worked great after the next storm. I was blowing snow for two hours and it worked great. This would have cost me about $200.00 if I would have taken it to a shop.

Item was exact fit had a timely delivery time very easy to assemble on my unit well done all around

The inside diameter is 12mm not 1/2". This product is mislabeled. (12mm = 0.472441 inches , close but will not easily connect two 1/2" metal shafts.)

A sturdy and practical alternative to expensive steering shaft u-joints when a larger dead-band isn't a problem, and both rotational speed and duty cycle are low.

This doesn't fit on a 1/2 inch shaft. It appears to be a metric size. I guess that because it came with no set screws and only metric set screws would fit. I'm disappointed that I wasted valuable time waiting for the wrong thing.

The ID is not .5” and the set screws it comes with aren’t even the right size. They fall right through the threaded hole. The overall fit and finish is poor. It was hand assembled complete with complimentary Hammet marks.This is a $5 part sold for almost $18 at time of purchase. Stay away. Its garbage
