5. Operating Instructions
5.1. Using the NT800 Rivet Nut Tool
The NT800 is designed for installing threaded rivet nuts with an innovative auto-release system.
- Prepare the Hole: Drill a hole in the workpiece suitable for the chosen rivet nut. Ensure the hole size matches the rivet nut's specifications.
- Attach Rivet Nut: Open the handles of the NT800 tool and screw the rivet nut onto the mandrel until it is fully seated.
- Insert into Workpiece: Insert the rivet nut into the prepared hole in the workpiece.
- Deform Rivet Nut: Close the handles of the tool firmly and continuously to deform the rivet nut until it is securely fastened to the workpiece. The tool's leverage system assists in this process.
- Auto Release: To release the used rivet nut, simply open and close the handles continuously. The innovative auto-release system will effortlessly unscrew the mandrel from the installed rivet nut.
- Attach Components: Once the rivet nut is installed, you can attach components to the workpiece using a bolt that matches the rivet nut's thread.

5.2. Using the NT200 Rivet Gun
The NT200 Rivet Gun is designed for blind riveting applications, featuring a 360° pivoting head for versatile use.
- Select Rivet and Nosepiece: Choose the appropriate rivet size and install the corresponding nosepiece on the NT200.
- Drill Hole: Drill a hole in the materials to be joined that matches the diameter of the rivet.
- Insert Rivet: Insert the rivet's stem into the nosepiece of the rivet gun.
- Position Tool: Place the rivet head firmly against the materials to be joined.
- Operate Tool: Squeeze the handles of the rivet gun together firmly and repeatedly until the rivet stem breaks off, indicating a secure connection.
- 360° Pivoting Head: Utilize the 360° pivoting head to access confined or awkward spaces, allowing for riveting from various angles (perpendicular, horizontal, etc.).
