Rivets?

Interesting......
My wife's Ocean Kayak Yakboard....???...

Thinking that pop-rivet heads would either "pull through" the boat wall as they were tightening.....or pull-out later.....I never even tried them

To mount a rod-holder, I bought those rubber-sleeved bolts (they HAVE a formal name, but I don't know it...I just went to ACE hardware and found them)

Anyway....a bolt with doublel-washers and sleeved with rubber in between the washers.  You drill a 3/8ths hole....stick it in, and as you tighten the bolt it expands the rubber sleeve to grip (and seal) the hole.

It worked.

But, interested to learn that pop-rivets work.

Judd, I think you are talking about "well nuts"

Yes they are well nuts or nutserts

Washered stainless machine screws work great, but when it comes to blind rivets the tri-fold type  are the only ones that I've ever seen recommended for use on poly boats.
