Skid Plate Bolt Size & Thread

[67BroncoG1]

I am trying to install a factory transfer case skid plate on my BaseSquatch but it doesn't have threaded holes were the plate attaches to the frame rail. The holes are there but they didn't weld a nut on the inside and there is no way to get and hold a nut in there. I'm thinking that I'll have to use a Rivnut in those holes and want to order the correct size. Does anyone happen to know the size and thread of the factory skid plate bolts? I searched and couldn't find the answer and I'm traveling so I can't just grab a bolt and check it.

Thanks in advance. Beer is on me for the correct answer.

They come from the factory with the clips that have a nut built in. Not exactly a nut but it catches on the threads of the bolt. Hopefully someone will recall the name of these clips.
It is not a welded nut.

I believe factory uses a 12 mm bolt maybe 25 mm long.

Looked it up and the name is ...... "nut clip" pretty genius

I have 2 left over from my replacement. I can take a picture of one if that will help or see if they have any numbers on them.

Thank you both! I’ll see if it shows on the Ford parts diagram.

No markings on them.

Here's what a nut clip looks like: https://m.media-amazon.com/images/I/71lsY3pPVBL._SL1415_.jpg.

I'm familiar with these things because they use 'em a lot on body panels on BMW motorcycles. They come in many sizes. Maybe your local Ford parts guy can help you figure out what size will work on the skid plates on your Bronco.

I ordered two of those from Amazon last night. I already have the bolt so this should do the trick. Thank you all for your help.

They are definitively M10x1.5.
