Ye thats what I thought, they are ok really for the money. I had one on my Y axis for 2.5 yrs before it snapped and it had done some hard work, infact my Z axis has still got the original one on from when I bought the screws nearly 3-4 years ago now.

That said I do prefer the Jaw type my self for a few reasons but the ones I've experienced have been ok for the money and I wouldn't waste time trying to make them which I easily could.!

Edit: Hank if it's the other DC collar then I can machine them for you.
