Rear seat mount bolt?

Does anyone know the Toyota # for the 4 bolts that hold the rear seats to the truck. M10 stepped bolt. I tried Toyota's site but ended up with the wrong one. Had one strip when reinstalling back LH seat. Thanks.

 

Take one out and go to the local hardware store, lowes, HD, and match it up.
Grade 8 bolts or. Better.

 

Last summer doing an VHF radio install had to pull my LH rear seat. Mine did the same thing during the reinstall,bolt galled almost couldn't get it back out. Ended up using a tap and die to chase the threads on both and reinstalled with anti-sieze. Sorry I cant give you a P/N but maybe you can do what I did.
