What Prevents Trailer Hitch Install Hardware from Threading into Weldnuts of Vehicle

Question:

I’m having trouble getting a couple of the bolts to thread and I’m a afraid I screwed it up some how. I cleaned the treads before installing and everything I followed the videoand I tried the old bolts they go in no problem. What am I doing wrong? Thanks

I don't know what hitch you have so I can't determine what bolt size you have and therefore the correct thread tap but what you need to do is use a thread tap to clean out the threads so that you can install your hitch hardware. This is a very common problem unfortunately.

You could start with the Tap Wrench Kit for Standard Pipe Sizes - Metric - 6 Pieces # PT22FR to determine your bolt size.
