Looking for T-nuts with M6 bolts

I need to mount some bicycle fork mounts on the front rail of a 22 TRD Sport. Unfortunately the fork mounts I purchased have a hole size that won't fit a M8 bolt.

I've found T-nuts with M8, and T-nuts with 3/8" bolt holes.

I'm looking ones with M6 (if they exist). Does anyone make them, and are they reasonably priced? Or is there something else I should be looking at from one of the home improvement stores?

I guess I could drill out / widen the holes on the fork mounts if I have to, but I'm surprised I can't seem to find something I can use.

Thanks!

 

I did a google search for “m6 t nut” and found many. I might be misunderstanding what you are asking for.

Is this what you're looking for?
See @MannyS's response.

 

Nuts specifically designed for the rails of the Tacoma and Tundra.
Sure, you can find nuts, but dimensionally, they are either too loose or they make grooves in the rail.

I do appreciate the responses I have recieved though.
Thanks people.
