Default Cross threaded bolt hole in hood. Any way to fix it?

I went to install some hood dampers last night and ran into an issue. The passenger one went on with no issues. However, while I was able to get the bolt on the driver's side out with no issues, upon screwing the bolt back in, I was unable to get it to go in more than half way. It gets jammed and won't go any further. It seems like the hole is cross threaded all of a sudden.

I tried the passenger side bolt with the driver side bolt hole and it wouldn't go in either. I'm afraid to use a torque wrench to get it in further as I do no want to bend/warp the soft aluminum of the hood. *Maybe I'm over thinking that part?*

So as of right now I'm unable to get the bolt to screw in more than 1/2 way.

As I see it now, I have 2 options:

1) Torque that bitch in and forget about it

2) head up to the hardware store and get a bolt that is about 1/2 to 3/4 the length and hope it gets secured enough to hold the tensioner on

Are there any other solutions I should be considering?

Take it to a shop and get it re tapped?

What's that supposed to accomplish? Oh nevermind, I see what you were thinking.

If you continue to cross thread the bolt, my bet is that it will shear all the threads out and you will be left with zero holding power. I've done it before.

Get a tap and clean up the threads.

If you already haven't done anything about this, I would suggest re-drilling first, to a larger size, and then re-tapping the hole.

If you re-tap the hole without re-drilling to a larger size, you'll have a really loose fit for your bolt / screw, as tibug said.
That may not be possible, depending on what is attached (I'm thinking hole sizes), but it's the best option if you want the connection to be as strong as it was before.

On the other hand, using some loctite with a shorter bolt might do just fine. Depends on how strong the connection needs to be, which is the call that you'll have to make.

Drill to larger size, tap it, put helicoil in to reduce size of hole back to original size, put old hardware back in.

That is if you haven't fixed it already.

since your able to start the bolt in...as other people said use a tap and clean up the threads. if you have a harbor freight, i bought a complete metric set for 15 bucks. that thing is cheap and i wouldn't rely on it for threading fresh holes, but it has saved my ass multiple times on cleaning up threads.

Thanks for all the input guys. Sunday morning I headed up to Autozone and picked up a tap and die set for $9. I was prepared to buy the complete metric set for $40 but they happened to have a smaller set that had the exact size I needed (M8-1.25 x 25mm).

It did the trick perfectly. After ensuring everything was aligned straight I was able to get it screwed all the way in a couple of times. It pulled out quite a bit of metal and cleaned up the threading nicely. After that the bolt went right in with no issues. Problem solved!

Thanks again.
