Threaded holes under 2017 totota tacoma pu bed trim

Toyota 2017 Tacoma. There are three sets of threaded bolt holes in the interior of the pu bed, only visible after removing trim. All are above the accessory rail. M6, but not standard thread (coarser). What size, and where can I buy these bolts.

 

Ive always had good luck with Ace hardware when it comes to odd metric bolts.

 

Metric thread is 1.0, 1.25, 1.50 and 1.75 etc. There is no fine and course like standard. Ask the guy if you can take a handful out to the truck.
Anyone working on cars and trucks needs one of these or a different version of a thread/dia guage. If you walk into a parts store with these you'll be a hero.
