Troubleshooting Hitch Install Bolts Not Threading Into Frame Rail Weld Nut

Question

Question:

Ive spent a few hours trying to install this, and I cant get the bolt in the weld nut. I tried the WD-40 trick with a wire brush, and the bolt wont even bite on the nut. I brought it by my mechanic, and he said he thinks its the wrong size bolt. Any chance I was sent the wrong piece? I bought item number 75547 Thanks!

We get this question quite a bit and the issue is really that the threads end up with quite a bit of corrosion and dirt which prevents the bolt from threading in. I attached a couple help articles that cover cleaning out weld nuts for you to check out but typically using a thread tap will get the threads cleaned. The size bolts are M10X1.25X30 CL8.8.

The weld nuts on your vehicle will likely have to be cleaned out. Over time the threads can get packed with gunk and make it seem like the bolts are too large when really they are not. Use a spray lubricant such as PB Blaster and soak the weld nuts.…
