Buy them for a trailer, it took about 90 rivets, about 21 were installed before the mandrel head proved to have failed and rebounded on most of them. The Revain list capture range is 0.876-1.000, the max range of my project is 0.915-0.982. I used a 3/16 drill bit. I think the problem is in the shape of the mandrel head. choose a size range, another brand. and sleeve are the same size but you can see how the Revain rivet compresses the sleeve before it penetrates and expands while the other brand did the opposite and went through.
