Stainless steel or not stainless steel? --- that is the question

After having taken about 4hrs, having to use a mini hacksaw blade, to cut through the severely rusted bolts and nuts securing an ex bump stop mount on my Series 3, I am wondering if fitting the new bump stops using stainless steel nuts and bolts would be the way to go? Would this minimise the corrosion in future??
 
In a nutshell yes.
I've recently had to remove and replace a rear bumpstop on my 110, fitted using stainless steel nuts and bolts 16 yrs ago, came undone easily.

Couldn't gain access with a larger hacksaw and did also use chisel and hammer. I'm getting there ---- learning a lot.
Thanks for your response Flossie ---- I guess it's stainless steel going forward!!

Worth a read.
I use a lot of stainless steel fastenings on the boat & also to replace bits on my Range Rover.
When I rebuilt my BSA A10 30-odd years ago I used stainless throughout. The beauty is no corrosion appearing from under washers as you would get with normal stuff & everything comes undone.
Using lubricant I've never had an issue but - albeit very rarely - I have experienced galling on unlubricated stuff & the only answer is to cut them off & start again with a new nut & bolt

Ratae, thanks for that ---- as you say certainly worth a read. I'll take my time tightening the nuts --- no power tools!!
 
Didn't read the article, couldn't be bothered, but stainless is great for non structural and when joining steel stuff together. So ideal for bump stops.

Don't use for body fixings, or holding on important stuff, like springs, bumpers engines etc.
 
I used stainless as much as possible on my rebuild but be aware that stainless bolted to Aluminium without
Dulac or fibre is the worst case for galvanic corrosion between the two components,

Club hammer and a sharp cold chisel, and a 4 inch angle grinder, are essential tools for Land Rovers.

Stainless nuts and bolts are probably good for that, or just plenty of Copperslip on new ordinary bolts.
 
I thought about stainless for my build but my current feeling is to used zinc plated bolts and copperease.
I am not keen on stainless for most stressed applications and corrosion can be an issue between metals.
Not decided yet but this is certainly the way I am thinking at the moment.
