So I was driving down the hwy 2 days ago and heard a noise like I ran something over and it went under my truck, didn't think much of it till I got home. Well turns out one of the mounting bolts for the break caliper on the passenger side came unscrewed and is now gone. I called autozone to have them order a new one but they ordered the wrong one. So I showed them what bolt I needed and they said they couldn't order it WTF? So I went to Ace Hardware and found a bolt that will hopefully last me till I can find the right one. Anyone got any ideas where I can order one online? I would like to use the dealership as last resort because I know how expensive they can be. Again....its the MOUNTING bolts not the super long caliper bolts, has one on top and one on bottom. If anyone can help me with finding one that would be great..thanks. OH YAH,....on my T its a 18mm.

Your best course is to figure out via markings on the head or via the dealership what grade bolt it is, then go to a bolt and screw supply house and get one the correct size and grade.

Had the same thing happen to me but the stealership wasn't to bad on price it was like $2.50 or something and they had it in stock turns out on mine when the stealership did the brakes before I bought the truck they didn't get the upper bolt tight

So heres an update...I figured I wasn't gonna find it anywhere else not even online...I tried, so I went to the stealership and had them order the bolt. Well Nissan upgraded that bolt to fine thread during 04/2007 and my truck was made in 03/2007 so when I said it was an 07 they ordered the wrong bolt....told them that the bolt they got me didn't work and the threads where wrong...so the Nissan guy did some digging around and called Nissan for me and finally 2 days later got the right bolt. it was like $2 and some change...not bad being from the dealership considering the bolt that was wrong was like 5 bucks. So now I got the right bolt in and good to go.

Just to help others who may reference your thread, I installed M.Y. 2008+ calipers on my M.Y. 2007 Titan, build date 11/2006, and the caliper bolts were the same threads. I find it odd that your thread pitch was different. The difference I saw was the bolt head type.
