fender bolt size ?

Can anyone easily tell me what metric thread the 90080-11220 bolt shown below is?
trying to source a fender mounting kit to help with my fiberglass isntall.

 

What did you end up using to help with install of fiberglass if anything? Also did you ever figure out what thread the 90080-11220s are?

 

Just an educated guess. The hex on the fender bolts are 10MM, while the thread is M6-1.0. Most of the truck is the same for a 10MM hex. Length unknown.

 

Thank you sir! I’m just trying to figure out what the bolt size is for the ones with factory welded nuts on the backs, like the ones under the hood attaching the fender also where the fender attaches to the door. I think those might be M6-1.0 also

 

Most likely. The next size up Toyota uses is M8-1.25. I've not found any M5-0.8 yet.

 

Good looks, I’ll get both sizes to be safe I’m sure it’s M6. Thanks again
