Review on Lixada 4 Stainless Steel Kayak Rail/Track Screw and Track Nut Hardware Gear Mounting Replacement Kit for Kayaks, Canoes, Boats, and Rails by Joshua Nation

The product looks high quality. The rail inserts fit perfectly into Railblaza's Versatrack kayak rail system. The screws are too long to attach grommets, spikes or similar, so you'll probably need to buy shorter ones. You can see in my photos that the screw is fully screwed in and the thread is still 3/4. I will update the review once I get the kayak out and see the quality of the metal (several reviews mentioned rust). Very expensive for 4 bolts and washers but if you look around very few companies sell them. Demand and supply.
