I read on here that molybdenum sulphide anti-galling compound is best choice to lubricate my turnbuckles but couldn't find any. Also, haven't found any corroboration on the internet that Molybdenum Sulphide is any better than any other greasing compounds to prevent galling so hesitate to spend money on something that might not be entirely necessary. So, out of the following products which I have to hand, which is going to be the best?

1) Zinc Chromate paste
2) Silicone grease
3) Graphite Grease
4) Lithium grease

I'm leaning towards the silicone grease, partly because it is transparent and so will not risk marking the sails.
 
I'd probably go for the lithium grease (mine is white in colour).

FWIW the rigger, Big Nige, at Suffolk Yacht Harbour lent me some Tef-Gel when I was renewing my rigging - a little goes a long way.
 
Yes, I considered tef gel but very expensive and I already have a garage full of different types of lubricant which i would prefer to use if i can. I've been reading up about the causes of stainless galling and haven't yet found any convincing reason that tef gel would be any better. Stand to be corrected though!
 
I use silicon grease on mine but they are chromed bronze so don't suffer from galling. I also used to use it on stainless turnbuckles and never suffered galling. I suspect just about any type of lubrication would assist, galling is a fairly rare phenomenon.

Not particularly true. Possibly that your fittings are not a particularly close engineered fit. Or are self lubricating materials
At work on subsea wells we use swagelok goop, or silicone grease on stainless steels....
Whichever is to hand. Any lube is better than no lube....
 
Sorry, my bad grammer.
I get problems with galling at work on a regular basis. Normally on stuff that has been submerged for a few decades though, or some idiot has overtightened in the first place.
 
Research by an ex-colleague at Shell found that molybdenum disulphide was the best palliative for galling and Shell marketed a product based on his findings for a while. It was a heavy grease with a high MoS2 content.

However, the British Stainless steel association recommends PTFE http://www.bssa.org.uk/topics.php?article=13

Just about everything you would ever want to know about galling is in this article http://www.nickelinstitute.org/~/Me...lingCharacteristicsofStainlessSteel_9006_.pdf It also suggests MoS2 for a wide range of temperatures.
 
These are the best lubricants in my eyes to prevent Stainless Steel from Galling (which it will probably do when you least want it to if not lubricated)
1.Nickel Based Anti Seize like Loctite 771 Nickel Based Anti Seize like Loctite 771 (should be Nickel not Copper based for Stainless) - best lubricant
2. Lanotec or Prolan Lanotec or Prolan - a good lubricant and the best thing for improving the corrosion resistance of the stainless to salt water (sheep wool oil - great stuff)
3. Tef Gel Tef Gel - a good lubricant and the best thing to prevent Galvanic Corrosion between dissimilar metals such as Aluminium and Stainless (Masts etc)

You can avoid lubricant if the hardnesses of the stainless nut and bolt differ greatly - such as 316 Bolts with Duplex 2205 Nuts - but that is a very expensive option. Some like using 304 nuts and 316 bolts in this way but no guarantees and you don't want 304 fasteners on your boat if you can help it.don't want 304 fasteners on your boat
