Stainless Steel Plenum bolts

Recommended Posts

After raiding Simons supply of SS nuts, bolts and washers, Dad sent me up about 3kgs of replacement SS nuts bolts etc from his owns Hot Rod stocks which is awesome. A great project to eventually have an almost rust free car! He asked me if I needed some odd sizing requests and hes found some same sized plenum bolt replacements. But I am wondering if I can use them. Will the metal react? Strong enough etc etc. Even though I have refurbed mine, boy all polished up the SS ones would look like little diamonds in there :ph34r:

Yes or NO ??

Cheers

Stainless will slightly react with the aluminium in the plenum, and they will ceize a little after some time.

Loctite on the threads should help with this.

But what are you putting heavy stainless bolts on a super light Sport 350? Plenum bolts could easily be aluminium. Much lighter. :ph34r:

I have the methodology on mine that if it needs to be really strong.. use stainless. If it needs to be fairly strong, use titanium, if it is just holding stuff together.. use aluminium.

This doesn't apply to the specialist bolts in places like the brake calipers, which need to be 16.9 steel and stuff.

"..diamonds are a girls best friend..." - Oh man ,oh man- Kylie do you really want to make it a 'girly-toy' ?! I know you love fine arts an a clean look, but as i have seen so much real sportscars in the Le-Mans 24 hours over the years. None of them look clean on the next morning -But all are fast and impressive!

Thank gents, well I figured these bolts should be quite strong, so next best option SS with loads af anti-seize etc on the threads.

Gunter - Diamonds are a womans best friend, but I promise you it wont look like a girly sparkly car, just well presented is what I aim for. :lol:

As stated stainless (chrome) and aluminium are on the complete opposite of some electrical metalists rubbish table so they can react - called a galvanic reaction. Same way as batteries work (2 different metals and an electrolite ie water in this case). In the engine it shouldn't be a problem at all, infact I've never expereienced this phoeniminan at all, mainly becuase it doesn't get enough moisture/water to complete the reaction.

People used to karp on about it with the Elise (mostly aluminium construction) and I never knew of an issue - I use plenty of stainless bolts into ali without a problem - however I do use copper grease which is supposed to cure the issue by acting as a barrier between the 2 metals, for the sake of 2 seconds why take the chance ?

As for strength have a quick butchers at this :

Basically avoid using 'normal' stainless bolts on load bearing and brakes, if you REALLY want to there are companies that make stainless fixings to grade 12 but at a cost, naturally.

But to be fair I usually use A4 because it has better mechanical properties than A2.
