Mast Electrolysis

[cvondo]

I am refurbishing my mast. I was looking for advice on how to mount hardware on the mast without electrolysis resulting especially from the ss screws. An aeronautical engineer recommended red lock tight and not to use tefgel for longer durability. He also said to use electrical tape on the mast between the ss appliance and the mast. Any other suggestions
? Or comments? Thanks chris

"Electrolysis" is the wrong word you mean galvanic corrosion. Use the tufgel and nothing under it. Engineers over think things I should know I am one lol. Galvanic corrosion is not a big deal with alum and SS even though they are not close on the scale. It has worked for as long as I can remember which is way longer than i want to admit.

Big fittings (winches, goosnecks, etc.) = pad + paste/gel.
Small fittings = paste/gel.

Alu rivets for non-load carrying instals.
Monel for load carrying ones.

!ALWAYS REMOVE! (punch out) steel cores after rivets done. Often not done by amateurs and bad riggers.

Less problem on anodized masts.

As long as the SS fitting is small vs. the mast (the mast is the less noble=corroding element) and you do your job, well expect no problems.
