Installing a 1/4-20 rivet nut is a quick and easy process that can be completed in just a few minutes with the right tools. First, you'll need to drill a pilot hole through the material you're attaching the rivet nut to. Next, insert the mandrel of the rivet nut tool into the body of the rivet nut and screw it on until it's tight. Then, insert the tool into your drill and set it to low speed. While holding the tool steady, slowly start drilling into the pilot hole until you feel resistance. At this point, stop drilling and continue to hold the tool in place for 30 seconds to allow the adhesive to set. Finally, remove the tool from your drill and unscrew it from the body of the rivet nut. That's all there is to it!
