I used these casters under a portable washing machine made in China. I measured the old studs and knew they were 10mm. The list shows that the studs on these symbols are 3/8. These two sizes are very close, so I figured I could get them to work. The fact is that these wheels have a thread of 10mm x 1.50mm. The nuts they supply are maybe 3/8, I can't say for sure, but I've used them successfully. The wheels fit perfectly. Can't comment on durability as I just received it.
