Bolt size for truck bed rail system?

Does anyone know the bolt size for the truck bed rail system in a tundra? I have some stripped bolts that ill have to take out. I need to get some new ones, but I'm not sure what size they are?

 

6mm

 

Thanks. Anyone have any tips for removing those stripped bolts?

 

Bruh I'm right with you. I should had tapped those inserts before cranking down on them screwa

 

Had an issue with that bolt stripped too. Used an extractor bolt kit. Came out relatively easy.

 

Or u can use a dremel cut a slit, insert flat tip and unscrew it

 

that dremel cut sounds like my speed. Never used a bolt extractor before

 

They are really easy to use. Drill the hole, tap in the extractor, and remove the damaged bolt.

 

Got new screws, tapped the threads, and they finally fit perfect with no stripping

 

Just had a similar issue. I drilled the head off with a large bit and used a pair of pliers to unscrew what was left. Did you replace with factory screws? If so you happen to know the part number?

 

I did replace with factory screws. As far as part number I just went down to dealer. They were not that $$$$
