![]() Sherex’s Flex-5 line of spin-pull tools is hydro-pneumatic, as the tool uses air and oil to install the part. ![]() This tool is also referred to spin-pull-spin as explained in the two sentences before. ![]() The tool then spins the opposite way to release installed rivet nut. The rivet nut spins itself on to the mandrel, and then the mandrel pulls the threads of the rivet nut on to the base material, installing the rivet nut. Spin-Pull Rivet Nut ToolĪ spin-pull rivet nut tool installs rivet nuts by pulling back its mandrel, rather than spinning it back. A hydro-pneumatic spin-pull tool is capable of installing all sizes between M3 to M10.įor a job that is consistently is going to use one part and one size, a spin-spin rivet nut tool would be a solid recommendation for the price. For instance, Sherex’s SSG-802 spin-spin tool is capable of installing parts with #10, ¼”, M5, and M6-diameter threads, and the SSG-803 is capable of installing 5/16”, 3/8”, M8, and M10-diameter threads. Also, depending on what kind of spin-spin tool you purchase, it may often be limited in the thread sizes it can install. The installation base material can vary in thickness, but it is recommended that the rivet nuts being installed are thin-walled steel, aluminum or brass. The benefit of using spin-spin tools is that they are less expensive than spin-pull and can often be more lightweight, but its capabilities aren’t as complete as the spin-pull tool. In order to both maintain tool integrity as well as ensure proper installations, it is recommended that spin-spin mandrels be lubricated with wax. After installation, the tool’s reverse trigger must be pressed to separate the tool from the now-installed rivet nut. The torque, driven by an air motor, ramps up continuously until the rivet nut fully collapses. Spin-Spin Rivet Nut ToolĪ spin-spin rivet nut tool is an air-powered tool that, once a rivet nut is secured onto it, utilizes torque to spin its mandrel inward in order to collapse the rivet nut. Let’s go through the differences between spin-spin and spin-pull rivet nut installation tools. Two of the most popular non-manual options are air-powered tools that install rivet nuts through either a spin-spin and spin-pull action. While small-volume applications may often result in a manual hand tool being the best choice, larger-volume installation projects may require more robust tooling. When it comes to rivet nut tooling, there are a variety of different options.
