Stretched bolt - WTB?

[wing0]

Did something dumb today.
While doing rear brake service, I put back the bolt on the caliper bracket and overtorqued one of the bolt and stretched it. I kept thinking, wow this bolt sure is hard to tighten with my torque wrench :razz:

Anyways, it's a honda and the bolt is M10 x 30 flange bolt.
Is it possible to get it somewhere other than Honda, like hardware stores or they are different quality?
I have not damaged a bolt like this before, but definitely want to replace it asap as I only have one bolt at torque spec.

Go to homedepot and look for an M10x30 flange bolt. Personally though i'd just call up your closest dealer and ask for a price. Cant be more then 2-3$

Hi,

If you don't want to get a bolt from Honda, you can try Fastenal. There should be a # stamped on the head of the bolt, that is the strength of the bolt, will be either 8.8 or 10.9. The store will also need to know the thread pitch of the bolt, 1.25 or 1.5 threads/mm.

You should be able to get one at pretty much any automotive store.

Im doing my own serciving soon or at least learn to do. i want to dk thr badics like change oil and filters but the brakes is probably considered intermediate to advanced level. Im curious what you wete doing? Like bleeding the barkes whick i asse us changin the brake fluids? If so how often should one change them and how dangerous is it i.e will the brake fluid be pent up and spray into your face like pressureized gas or not? anyway i. Lookin into getting a tool set as well to start doing basic maintenance things first tgen later mught get into the barkes and other stuff.

Sorry for the derailment but gotta asm to learn.

In all my years of working on cars and aircraft I have never seen a bolt that was stretched beyond use. I would like to know how you determined it was stretched?
Do you possibly mean that you "stripped" the bolt and damaged the threads? If so, you may also have damaged the threads in the caliper housing (or was it a nut on the end)
Regardless, never go to Home Depot or a hardware store for automotive fasteners. Vehicle bolts are different in material and strength and depending on the application, it could be very critical. Always go to the dealer because they know what grade blot is needed for the specific applications. Some auto parts stores will have a catalogue and can cross reference and get you one too.

I didn't strip it, I was trying to tighten the bolt holding the caliper bracket and in the manual, it calls for 60ft-lb of torque. I went at it, but felt it took extra long to get the click. Took it back out and it was like that.
I did the other bolt without problem and I also torque the wheel nuts afterwards with the torque wrench fine. So it doesn't look like it's the torque wrench fault. Maybe just a bolt that was losing strength over time.

I'll just get it from Honda, no big deal. Rather be safe than sorry.

I was doing caliper disassembly to clean up all the junk/rust on them. The brake pads weren't moving as freely as it used to on the slider. I did not bleed the brakes. I don't have to do it this time since I will have to change the pads in another 15k or so which I will do it then.
My tools were just socket sets, torque wrench, breaker bar, silicone brake lubricant.

I would suggest you to research on bleeding the brake process. Usually it requires two people to do it, one pumping the brake while the other bleeding one corner at a time. There is also usually a specific order you do which is in the service guide and may differ from car to car.

Like I said, in all my years I have never seen this happen. You are a master, I guess.

From a turbocharger (your linked image), where it gets so hot, I could understand this happening if someone tightened it when it was hot but, a cold grade 8 bolt on a brake caliper?
