I received this cole jaw set and immediately put them on my Nova G3 chuck. The jaws fit the Chuck perfectly, mounted the Chuck into the lathe and gave it a spin. Everything was in balance as expected. I mounted a bowl that I had been working on and the jaws held the bowl quite securely. Unfortunately, I have a small lathe and was unable to put the expansion jaws onto the chuck to see how they would work.
This set came with all the rubber bumpers, screws, washers and an Allen Wrench that is needed for use. The quality of the jaws of his peers to be quite good there were a few marks on the jaws from pieces rubbing together during transit. These marks are completely superficial and in no way will hinder or interfere with use of the jaws. Very pleased with this product.
