I posted this in suspension as well, but its a bit slow there so I thought someone here may know.

Does anyone know the grade that honda uses for the civic\integra suspension hardware? Bolts, nuts etc?

Thanks.

 

I believe it's grade 8. Just curious, why you want to know?

Thanks, pretty much just curiosity.

 

10

I wasn't aware there was a 10:

For replacement bolts on suspension, I always use 8. Never use anything off the shelf at HD or Lowes.

 

My car came from back east and I am sure the stock bolts have had it, so I am getting all new hardware from honda, might as well replace these while I do the bushings.

Thats why I wanted to know the grade Honda uses.

 

I saw a 10 stamped on the head of one of my suspension bolts 2 weeks ago. I live in Canada so maybe there's some difference. The clostst thing I could find at a Hardware (I snapped the bolt and needed a quick fix) was an 8.8 headstamp. So I need to go to Honda and get a stock replacement asap.

I have a feeling that there are two scales for measuring the strength / grade of bolt. Sorry for any confusion and feel free to flame away if i'm wrong.
