Default Bolt Strength Guidelines

I have a car that I am trying to build that was stolen/stripped. When I say stripped I mean EVERYTHING...

The problem I am now running into when putting it back together is I am not sure what kind of guidelines I should be following for bolt strengths.

For example, I have a Sparco EVO seat I want to install...but since I don't have the OEM seat bolts I need to go buy some...but I have a feeling a hardware store isn't going to have bolts strong enough for mounting something as important as a seat. What about stuff like motor mount bolts? I dont have OEM bolts to use for that either (nor basically anything else on the car).

I realize some bolts are special and will have to be dealer items, but for obvious reasons I would like to avoid that as much as possible. Does anyone have any guidelines I should look at for this important mounting hardware?

Go to the dealer and get some OEM bolts.

I'd say that's your best bet.

I feel your pain on the dealer thing, but for motor mounts, seats, and suspension, I would not use it unless it came from the dealer, or I found an identical one with an equivalent grade at a metric supplier.

I usually just go to local yards and get what I need. You can get just about any bolt, nut, or screw you can possibly think of for a good price. In some cases they charge by the pound and it's quite affordable. I've left with a backpack full of hardware for less than $20.

Hi.

if you go the hardware store route; get grade 10.9 for the crucial areas. its the grade generally used in the "it better not break or i'm gonna die" areas.

i vote for going to the junk yard; its the cheapest by far!
