I wheel my Weby's in and out of the garage when using and usually a few times a year one or more of the caps fall off and get lost. I've been thru at least a dozen original Weber replacements and a few others.
Nothing seems to last, until I tried some 3/8" metal shaft collars. They have a set-screw which really digs in and holds.

The ones I bought were zinc-plated, but SS ones are available from Amazon or an Industrial supply house.
3/8" is a tight fit. I had to use a ball peen hammer to tap mine on, but reaming it with a HS metal bit like a 25/64" should make it easier to slip on or remove.
Not the best pic, but at least I know my wheels aren't falling off.
