Screw Size Inquiry
 

Good morning all,

Last night, while attempting to install hood dampers, I over-tightened one of the 10mm bolt on the fender lining area and broke the top portion off...

Now I need a replacement bolt but having a hard time looking for the right size.. I attached a diagram for your convenience (#3 on the diagram), please tell me what size bolt I need to get...

Thanks!

M10-1.25x ___MM is the way to look for it. Metric bolts are measured in mm, not inches. Also on top it should have a number stamped in it. 8.8, 10.9 or 12.9 those tell you the hardness. Other than that if you had a comparo picture, or just bring it to a local fastenal and they'll be able to help you size it.

you'll also probably want a screw extractor to get the threaded portion you snapped off out of that hole. Unless you already took care of that.

Thanks!! Getting it removed tonight after work :)

That is not an M10 bolt. Bolts are measured by the diameter and pitch of the threaded portion. It was most likely an M5x1.25 or M6x1.25 bolt with a 10 mm head. Remove one of the other fender bolts and bring it to a napa to match it up.

yeah what ozzman said, bolts are measured by diameter not head size my mistake.

I did the same thing yesterday. Had a hell of a time getting the rest of the bolt out. Were you able to get a replacement and if so what size. May save me a few minutes at the store.
