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 Andre Tenk

I'm the only one here who actually used them for my anchor trolley (pulley block) system. If that doesn't work I can always widen the 3/16" holes to 3/8" using nuts. That being said, these rivets fit perfectly and feel very tight. The expanding end is 3/8" to 1/2" in diameter, lays perfectly flat and locks into place when expanded. Some people say that the shanks of these rivets broke early. I had no problems with that. Using a Harber cargo riveter with the correct diameter tip, I slowly and gradually pull the rivet out. After each gradual pull, I bring the tip of the rivet back up to the rivet and repeat until it fully extends and locks into place. I've made about ten of these rivets with 100% success. The rivet shank is perfectly flush with the rivet head and everything is very tight. Will this rivet last long? Just take a look.
