Can you confirm these work with a threaded bar? Most spring clips say they are not for use with a threaded bar.

Interesting. I have 1 inch threaded bar. They work. However not completely tight to the weight. That bothers me a bit but they keep the weight on the bar

Will this work with the an coaster max weights?

If the shaft for the weights is 1 inch, these clips will work. I looked on the page for the "coaster max" and could not find the size of the shaft. The photos on the coaster max page shows clips that appear to be the same as these spring clips but we cannot be certain. Not much of an answer. Best to confirm if the shafts are 1 inch.
