Was putting on my tow mirrors, drivers side went on perfect in about 5 minutes total (disassembly and re-assembly), the passenger side came off just as easy, went it place easy but when I was tightening it, the top mounting bolt broke, I figured I could hold it on with the bottom two until morning when I could run to Lowes and get a replacement, then one of the bottoms broke so I decided to take the last one out and on its way out, that sumbitch broke too!! I need to know what the name of this bolt is so I can ask for the correct thing in the morning at lowes. Here's a pictures of what it should look like.

 

You are probably not going to find this at Lowes. It is a speciality stud, and will probably have to be ordered by a fastner supply. Can you use the old studs from your old mirrors? I don't remember how they were set up other than that they were held with 3 mounting studs, built into the mirror housings.

I put Bestop trailer towing mirrors on mine and love them. You must of really cranked those studs to break all 3 of them. They are only a grade 2, so you can't reef on these type studs. Good luck

 

I actually didn't crank on them at all.. There was still about a half inch in between the mirror and the door. I'm guessing there was something already wrong with that batch of studs.. No reason that they should've broke. The drivers side, however, they should've. I cranked those babies.

 

I'd go to a scrap yard to try and find them. I forgot where I read it and I don't know if it's true or not, but I heard they should be torqued down to 20-30 ft LBS, so I did mine at 30 and haven't had any issues.

 

If you can find that metric thread, you can make one out of all-thread and a washer.

 

IF you knew how long a bolt to use, a straight bolt into the mirror would work also. The stud is there for ease of install. If someone held the mirror and you had the right bolts, you could do it that way also. The all thread idea is not bad and a simple way to do it also. Good luck.

 

It turns out no one from this town has even seen anything like that before. I went with the all thread method. It's holding up so far, and I don't see why it wouldn't continue. Thanks for the help!

 

How could you possible get a piece of all threaded rod to tighten down and stay?

 

Went to Home Depot and found the correct size/thread all thread. Cut it to the correct length. Start the all thread into the stud hole, thread one bolt on a very little amount, and another bolt to butt up against the first bolt so the all thread will thread in. Remove second bolt, and the first bolt was tightened down. Did this for all three studs. I don't know if you understand my explanation lol, but then it's just like installing the mirrors in the beginning.

The all thread acts as the studs and just torque them down.
