Installation Tip: One good way to install QUICK FIST clamps is with rivet nuts (aka Nutserts®). They are nuts that can be riveted into holes whose underside cannot be reached. If you search “rivet nuts” or “Nutserts®” you can find a range of sizes and installation tools. Many kits, including tools and an assortment of rivet nuts, can be purchased for less than $100.00 and the applications are broad. Alternatively, you may be able to find a local garage that is willing to install rivet nuts for you.
