The Cherry rivet is suitable for soft materials like plastic kayaks
The Cherry (tri fold) rivet splays out much much larger than a standard rivet allowing it to be used in less secure materials without pulling through.
This blind rivet can be used in places where you would normally use a nut and a washer on the underside but can’t get to easily. To install as you only need to access from the outside. A standard rivet gun will work to install but may require a few compressions of your rivet gun due to the long throw required to get the 3 arms to reach full width.
