The lever-forward design of NOVORIK rivet nut gun results in a 20% greater labor-saving efficiency compared to other similar 16-inch models. The tool-free installation design streamlines the process, enhancing efficiency, convenience, and saving time and effort. Each component is snugly stored in the box, ensuring tidy, portable, and convenient storage. NOTE: Novorik rivet gun works best with rivet nuts made of soft metal such as aluminium, iron and copper. However, you need to be careful if you are using stainless steel or other hard metal rivet nuts because they may damage the threads on the rivet gun, especially rivet nuts that are larger than M8 (10-24). Of course, we still advise you to use soft metal rivet nuts and other accessories with our rivet gun.
