Question:

My 38foot RV lost a lug nut, the socket size is 33mm, wheel size is 19.5. Cant seem to find anyone that has this size nut with a cover.

The socket and wheel size has no bearing on the correct lug nuts for your RV. In order to determine the correct lug nut for your RV you will need to remove one of them and take it to your local hardware store. At the store they will have a series of different bolts you can thread the nut onto which will then tell you both the diameter and TPI/pitch. For example, the Americana Trailer Wheel Lug Nut part # AM90049 works with 1/2"-20 lug studs.

I have attached our selection of lug nuts for you as well once you find out what diameter and TPI/pitch you need.
