A leveling leg for a refrigerator might have the same diameter and thread.
I don't know if you can buy bake elements "off the shelf" for your oven, but if not, the made-to-order option is a common alternative and similar in cost. Sometimes there's no other way to get an element replaced, but the good thing is that a made-to-order type will perform just like the the old one, and won't be some kind of universal one-size-fits-all compromise.
You may not even need the old element to ensure proper dimensions for the new one. When I had the element replaced on the '49 Westinghouse, the old one (a previous replacement) was a little smaller than the original. The made-to-order one was slightly larger, which was correct, but the parts house guy sent it back and asked for the same size as the one I left with him. So, it seems the manufacturing facility knows the correct dimensions for the various makes.
