A few months ago I bought a set of five new wheels and tires for my TT at a national tire dealer. Recently when I tried to remove the spare from my bumper mounted carrier manufactured by Stromberg Carlson, I found that the bolts and lug nuts were severely cross-threaded. I can't seem to find replacements anywhere; I've tried RV parts distributers, Fastenal, eTrailer, etc. Those of you with this setup know that it's important to have the lug nut so that it mates correctly into the lug hole on the wheel, holding it solidly in place. And that's why you need the fine-thread carriage bolt to match. Also, there's the convenience of using the same size lug wrench on the spare as on the running wheels. Has anyone ever had any luck finding these parts?
Per Machinery's Hand Book. Carriage bolts are only available in the Course thread series, class 2A. What you want is studs and the properly sized lug nuts to fit the threads on the studs. This stuff is readily available at most auto parts stores. NAPA for sure. Yours are probably welded to the mount. If so, they will need to be cut out or drilled out and the new studs welded in place. They may be just a press fit into the mount which would make replacement simpler. Press out the bad (old) press in the new. Many auto parts stores are equipped in their machine shops in the back of the store to do replacements such as this.
