How Mainly Nuts And Bolts For A Rebuild?

[allye 530 3 Cars]

The Rallye is going back together soon and would like to replace as many nuts, bolts and washers for stainless items.

 

I'm not after exact amounts! Just a approx, I'll over buy any way. It will be for bolting everything back to the engine bay, fuel tank etc (not suspension, beam, or engine)

 

I know this is a proper anul question but I know I would end up buying loads of the wrong size/amount !

 

Thanks! Ali

Are you sh*tting money these days Lots of stupid sizes for those bits, M9's are quite common.

Haha, not quite. But I want it to go back together properly, I'll see how many I'll buy if the cost is loads

Never come across M9, quite a bit of M7 to the delight of my Ford owning mates!

 

If you are buying stainless then you will want a selection of M6 & M8 nylon nuts and bolts of about 20mm long. This will get you started at least. Do not be ripped off on eBay, your local bolt place will usually be cheaper.

dont you have to be carefull about stainless bolts? eg they are not as strong as steel ones? or am i wrong

[Tom Fenton 1,548]

They should not be used on suspension or brakes for definite. The problem is that stainless work hardens and becomes brittle. Fine for none stressed applications, holding a bracket for something on etc.

yes you have, pug rod bolts though not really applicable to this topic

[Rippthrough 98]

Yeild strength of the most common A2/A4-70 stainless bolts is well under normal 8.8 grade bolts, so non-structural applications only unless you're prepared to do the calcs.

Don't forget the dissimilar metals reaction as well. SS can be troublesome when going into ally. Copperslip on the threads help.

Ha ha just read my reply i did mean to type M8 honest.

You'll need anti-seize on everything, specially any bits that get hot. Stainless is a bastard for seizing. Wouldn't it be better (and cheaper) to just get plated bolts?

[SurGie 54]

yes then cover then with either copper grease or thread lock which stops the thread rusting, thats what im thinking of doing.

Hi, Screwfix sell a good range of stainless bolts, nuts and washers. Not that expensive either.

[Cameron 16]

I bought all mine from Screwfix, just be aware that they're only grade 8.8 so you can't use them to replace bolts of a higher grade. The zinc coating on them isn't amazing either, mine started to corrode after only a few months but TBH they're so cheap it doesn't really matter.

I always hear people complaining about stainless bolts seizing, but after years of having stainless bolts on most my cars, iv never had this problem....

[Rippthrough 98]

It's when you're using stainless bolts into stainless nuts, if you don't lubricate them and they pick up on a little dirt or a burr it will weld the two together.

[allye 530 3 Cars]

Righto, get a selection of stainless bolts just for bolting non load things, (bumpers are on the top of my list!) give them all a good coat of copper grease.

 

Job's a goodun.

[Cameron 16]

Copper grease will probably be ok but you should really use a nickel anti-seize, specially if it's an important joint (like wishbone or something) or a blind hole, and extra-super-specially if it gets hot. I know I'm always banging on about stainless bolts but you wouldn't believe how badly they can seize up, you'll shear the head off way before you ever get it to budge.
