I lost a bolt doing a headlight upgrade on my 2.2. Does anyone know the size of them so I can get a replacement?

 

Easiest solution is to go to the hardware store, grab one of your bolts you have, and then go in and match them up.

Alternatively the dealership should have them.

 

I think its 10mm if I'm not mistaken

 

The head size is. I think OP was mainly concerned about thread size and pitch.

 

yeah they are 10 mm, i actually just realized i lost one also so i just went down to home depot and matched one up.

 

yea...exactly...i went into a Home Depot armed with only the information that it's 10mm and found it not to be that helpful. But I suppose I shall call the dealership because I don't really feel like taking another bolt out. Thanks all!

 

The standard bolt GM/Chevy uses for most equipment is an M6 x 1.0 bolt.

I just replaced my headlight bolts yesterday after they blew away during a storm, I used four M6x1.0 by... 20mm bolts and they fit perfectly.
