Hi All

I am restoring a bench where all the metal fixings had rusted. Some
joints have large barrel nuts and bolts and others bolts and inset
nuts.

I was thinking of putting something on them before refitting to try
and
protect them. I had a few thoughts...
- use something like vasaline but guess the oil would ingress into the
wood. - paint them before they go in. - given they are all M8 the rust
is probably superficial anyway so only need to deal with the thread to
tighten if necessary at some other point.


Anyone have any ideas on how to prolong the life of this?

Get some stainless steel nuts and bolts! :-)

They are surprisingly cheap now if you shop around (e.g. suppliers on
eBay)


I've got a cheap "stainless steel" Ebay gate stay that has quite a lot
of surface rust after a year outside. It actually looked like SS when
new. No metallurgical tests performed, maybe it is some kind of SS?



It happens if the alloy levels are too low; although unsightly, it
should still last much longer than mild steel. Abrade periodically with
steel wool and a bit of 3 in 1. (Or wet and dry plus oil, if the
geometry is more favourable for that).


I only got stainless because I find such maintenance too boring! (I
think I'm beginning to sound like Hucker - another visit from the troll
fairy seems imminent.)
