Re: Stainless Bolts

Since it's a two person job, I will see if the admiral will lube the nuts while I handle the wrench. Certainly dont want any galling. This job sounds more fun all the time.

I had no idea that stainless bolts would elicit such a torrent of information. I bet I spend more on gas than fasteners running back and forth to the bolt store to get the correct lengths.

Re: Stainless Bolts

I,don't know a thing about Duralac.I,have used TEFGEL for years with outstanding success I,even coat the aluminum with it where a stainless plate may fit over it,stops corrossion.

Re: Stainless Bolts

There is only one place in the USA I know of to get Duralac, Duralac Anti-Corrosive Joining Compound Tube
And it sure seems spendy.

Re: Stainless Bolts

Over 40 years we have used lanolin, Duralac and Tefgel. Lanolin is OK but it sticks and lasts less than Tefgel, and is very affected by temperature (from runny to very hard). Tefgel is best for fasteners that you might need to remove within a year (but it cannot be painted over). Duralac is the best for stopping corrosion permanently (we have stainless screws in aluminum and no corrosion after 20 years). It dries like paint to somewhat lock the crews in place, and can be painted over. For unpainted places, the only disadvantage is the yellow colour, although one can wipe off most of it, leaving only a tiny yellow ring visible around the screw heads.

Not finding any source of Duralac in the USA, I brought in 5 tubes and am now selling 3 on Ebay.

Re: Stainless Bolts

I bought our tube into Croatia in our stowed baggage and yep with no cabin pressure it leaked, must remember to use plastic bag!

Gave it to the Raymarine installer last week to put it on anywhere metal touches the mast on his install of a spreader camera, you guessed it i never got it back!!!! Aaaaaaggghhh!

Back in Australia now so i'll buy another ($50) tube.

I can attest to 35 years on mast installs with no corrosion.

Cheers Frank

Re: Stainless Bolts

I just read on another forum where a person working for a mast company says they prefer TefGel to Duralac. They used to at one time use Duralac. He didn't say what the reason for the preference was, but looking at the Safety Sheet for Duralac it is not a nice compound.

And we're supposed to put it on our nuts?
