A4 in FF

So I broke off the back bolt holding the turbo to the exhaust manifold. It cracked loose ok, but I could tell it was not coming out without a fight...

What grade are these bolts? I went to Fastenal to get a replacement figuring they'd decipher the marks on the top as I didn't recognize them as the usual metric grading. I was helped by a nice young woman who said the grading isn't marked. I told her the application and she didn't have a recommendation for me.

I found them for $7-10/each plus shipping. So my question is can I use a "regular" fastenal bolt, or will I regret that decision later in life?

Just be sure its a grade 8.8 or higher and you should be fine.

That's what I was thinking. Unless someone chimes in with a horror story that's what I'll grab.

I know you have them, you were the first place I checked. I thought about ordering until I realized it was $10 each, not for the set. With shipping it's just short of 40 bucks. I see that is the going rate so I thought I'd check to see what people thought. If I got a rash of replies saying use only the genuine bolts then I'd have to get over my cheapness.

Only thing I would be concerned about using a random bolt from the hardware store is the heat. Manifolds and turbine housings get extremely hot. If hardware isn't rated for many years of heat cycling it will fail prematurely.
