Hi Dave; Before installing the reefing hardware on Spirit I was concerned that #10-24 machine screws wouldn't have enough bite in the thin walls of the Dwyer DM-2 boom and thought rivets might be better. I checked with Dwyer, who said that either fastener will hold. I used machine screws with 3M Threadlocker (appears to be the equivalent of LocTite blue). It claims to prevent corrosion - only time will tell. Admittedly, I am more concerned about fasteners working their way loose then with them becoming frozen up by galvanic corrosion. I plan on taking one out in a few years to see how it's doing. Jim Poulakis M17 "Spirit" On Feb 28, 2009, at 7:57 PM, W David Scobie wrote:

I've purchased a new main for SCRED, my M15. This sail has two reef points so I'm in the process of setting up the boom to for the necessary second line.
For attaching the second eye strap, bullet block and clamcleat I'm looking for opinions -
aluminum rivet the items in place (as done with the other hardware); or, stainless steel screw the items in place?
If riveting in place, what 'grip length' for the rivet?
If screwing in place, what length of screw?
I've seen in other's posts to use 'never-seize' to avoid problems between stainless fittings and the aluminum. In the local hardware store i've found 'anti-seize' by PERMATEX. Are these the same products?
