Mainsail track rivets

[luismartins]

Hi knuterikt,

Thank you the link. Today I found a source in the UK with reasonable prices. Around €42 for every pack of 100.

In the product description they have:

Monel (nickel copper) alloy rivets
Corrosion resistant rivets for use with aluminium and stainless
Particularly suitable for marine applications, coastal, saltwater spray
Often used for securing fittings to sailboat masts and spars
Body: Monel
Mandrel: Seel zinc plated

Here is a link: http://www.shop4fasteners.co.uk/rive...ts/c-24/p-4600

I have one concern though. With the mandrel being zinc plated steel it will certainly corrode inside the rivet which is not good. Should the remaining of the mandrel be pushed out of the rivet? And if so, won't this make the rivet weaker?

What is the mandrel of the rivets you found in Norway made of, do you know?

Regards,
Luis

I always remove the mandrel, this is in accodance with Selden instrictions on mounting hardware on their mast, Using correct length rivet this is easily done using a pin punch.

I always use Duralac to isolate dissimilar metals. (I the UK company sells that to)

Even if your mast is not from Selden you should have a look at this http://www.seldenmast.com/en/technical_info.html Lots of useful information.

Hi knuterikt,

Thank you for the quick reply and the links.
The Selden rigging document is extremely interesting.
