Rivet Nuts

How to install AVK inserts?

• Quarter turn the AVK fastener on the tool mandrel and place it into the hole. Then, press the top trigger on the tool.
• Once the hole fill is complete, the AVK fastener forms its backside flange behind the parent material and then the tool stalls.
• Finally, reverse the tool and proceed to attach the mating component using the appropriate hardware. The entire installation sequence of the AVK fastener takes 3 seconds or less.

How to choose a tool that offers faster assembly and lower installation costs?

• Spin-Spin Tool - The rivet nut is threaded onto the mandrel of the pneumatic power tool and then inserted into the hole. When the tool is activated, the mandrel spins to pull the threaded portion of the shank towards the blind side of the workpiece. This forms a bulge around the unthreaded portion which then pushes against the back of the panel to create a clamping force and grip the sheet. Once the rivet nut is securely clinched in place, the mandrel spins in the opposite direction to unthread itself from the nut, leaving the rivet nut's internal threading intact.
• Spin-Pull Tool - Similar to the Spin-Spin tool, an air motor is used here to thread the nut onto the mandrel. These tools are great for plastic workpieces.
• Pull-to-Pressure Tool - This tool is almost similar to the above two except that instead of pulling at a specific distance, it pulls at a set pressure. If you are fastening metal or a hard plastic surface, a pull-to-pressure tool is ideal.

What end types are available on rivet nuts?

Open-end rivet nuts are ideal for load-bearing applications due to their large diameter head. The open end feature offers increased resistance to pull-out when reinforcing the hole. Whereas, in closed-end nuts, the thread area is enclosed eliminating leakage past the threads from either side of the application.
