bolt grade question
 

ok... i seemed to have lost a transmission mount bolt.... now the one that i have (takes 2) is a 10.9 grade bolt (metric) so i went to homedepot in hopes to find a bolt to work.. and i found a bolt that will work length and thread wise... but its only a 8.8 grade bolt... im not to sure on how much of a difference there is... my question is will i be safe using the 8.8 bolts on that... or should i just order the stock bolt from the dealer?? i know the trans mount takes alot of abuse... this is why im asking.. thanks for any help

Fastenel is up here by me, you can more than likely get what you need, or just PM SJsleeper, he seems like the kinda guy that would have that bolt.

Or junkyard searching.

Or just not worry about it.

Yeah i got 2 of them

hmmmss... can you part with one... since im not driving the car anytime soon... ill just use what i have to get the trans in... but are you goin to the next meet when ever that is... maybe you can bring me one... and ill buy ya a beer...

I'M probly meeting up with chris (nj torque) on 37 tonight. maybe u can get a ride out there or i can drop it off monday to you. i gotta see builder for a check on drum point rd monday so its close

^^ haha.. yea im in for the night tonight..if you want to drop it off thats cool... if not thats cool too i can always get it another time or at a meet... like i said... its gonna be a while before the car sees the road again...

Regarding your original question, I think 8.8's have a tensile strength/yield strength of 120,000/~90,000 or so. 10.9's are 150,000/130,000. Good move keeping it at its original strength.
