Chrome lug nuts

Does any one know the exact size of the socket that would fit the chrome lug nuts that hold the hub cap on the wheels?
They are the 2 that has the slot mark on the chrome caps.
The Winnebago gave with the coach a thin metal wrench that use to work but it is nothing but a very thin metal that bends very easy. It's just a bit larger than the wheel wrench that remove the lug nuts of the wheel. The last time I had new tires put on they must have tighten the 2 chrome nuts so tight I am unable to remove them with that cheap wrench that came with the coach. The size appears to be 43mm, but unable to find that size socket. Tried 1 5/8" socket but it just a little to big to grip the chrome lug nut.
I have tried every auto parts store in town plus Harbor Freight. Even tried a couple of semi truck garages, no luck.

  • It may be because of the age of my unit, but my jam nut covers are just tapped on and the wrench fits directly on the jam nuts.
  • They're probably 33mm. This looks more substantial, although if you need that much power to remove one, it could do with a dose of WD40
  • I had the same problem when I had new tires put on. The tire installer did not tighten one of them and I lost the jam nut on the short trip home. Not sure of the size, but for the front, I use an adjustable crescent wrench with a rag over the nut to prevent scratching. The rear would be a bit more difficult using this method.
