Review on 🚣 YYST 20 3/16" Deep Water Long Grip Tri-Grip Tri-Fold Tri Bulb Mounting Rivet - Aluminum for Installing Kayak, Canoe, Boat Accessories: Ultimate Watercraft Mounting Solution by Justin Sherman

I would not recommend this if you plan on assembling your gear and are going to be subject to any kind of violence. This is only good for the eye holding the rope in place, not the bungee holding your box, not the rod holder, not the anchor trolley. The figure shows that the rivets are much shorter than those of the yak. Notched rivet which means less attachment point/strength in your case. The quality is also not very good, you can eliminate multiple failures with rivets. Conclusion: get your yak gear. It's a PITA to unscrew a bad rivet and you just don't want to risk a bad rivet while you're on the water.
