Rub Rail rivet size

If anyone has replaced the rivets that hold the rub rail to the hull, what is the diameter and length of the rivets?

This may not answer your question specifically, but may help. This is what I posted in another thread when I had to repair the rub rail on my 25.

"Finished up reinstalling my rubrail today. I ended up using ss machine screws, washers and nylon lock nuts. 1/4 x 20 x 1 1/4"."

I replaced what was left of my rivets with stainless steel binding posts and a sealing washer. This avoids the globs of sealant inside the boat (detailed on page 3 of this thread:

I removed the rivets ,most were broken off anyway.
The rivets use a steel mandrel. Bound to fail sooner or later.
Also riveted from the inside. Poor design in my opinion.
I Drilled the holes out with a 1/4 drill bit . Used 1/4 stainless steel bolts from the outside.
Lots of 4200 sealant with a medium stainless fender washer and stainless lock nut on the inside .
My wife held the bolt on the outside and I used a Dewalt driver with a socket on the inside to tighten them down.
Cut remaing bolt off with a cutting wheel .
Then with a vinyl glove on my hand, covered the inside nut and washer with 4200 to give them a smoother finsh.
