20pcs 3/16" All Aluminum Tri-Grip Rivet, NALAKUVARA 3/16 Inch Black Long Grip Blind Rivets Kit with Water Proof O - Rings, for installing Kayak, Canoe and Boat Accessories with Thicknesses Materials

Great to use on my kayaks, this was my first attempt at using Rivets, I need to order more! Oh what to attche next!? Ha

I've used these to replace pulled screws in my trailer awning. So far, they have worked quite well. We'll see how long they last.

First pull they snap, they don't expand at all, pull stem breaks in first pull every time. They worked good to position my accessories, now I have to drill them all out, and put good rivets in. DON'T WASTE your time on this garbage.

what I expected

The gasket seal does not last very long. It is going to crack then comes off from the rivet leaving an unsealed gap between the kayak and the rivets.

I mounted a couple of scotty rod holders to my kayak with these and they worked Great. Just make sure you use some marine glue

A+

These rivets are junk, break on first pull, don't buy or you will be very angry like me, just a bunch of Junk, probably chineese made by idiots.
