Mast Cleat install - Question on rivet sizing

[Satch4621]

Hey Gang -

I will be working on a few boat projects over the holidays. First up will be to install a mast cleat.
I plan on using a some pop rivets. In order to purchase the proper size rivets I am trying to determine the grip range needed (thickness of cleat + mast side wall)

Can anyone tell me the thickness of the mast wall?
Thanks!

Wall Thickness: .083" (2.11 mm)

I used the 3M 4200 sealant behind the cleat, and fastened it on with #10 stainless steel sheet metal screws – I had to pre-drill the mast with small pilot holes.

Tag,

Thank you for the link and info. Your original post on installing the cleat was my inspiration.

Thanks again!
