Nut Installation and Usage

The internal oval design of the nut is standard. Follow these steps for proper installation:

1. Insert the chuck diagonally from the side of the nut with the smallest oval diameter.
2. Gently push the chuck to fully enter the oval cavity.
3. Once the chuck is inside the nut, install your fixture (e.g., milling cutter).
4. Disassembly follows the same steps (remove fixture first if applicable).

The priority is to ensure the chuck is securely seated in the nut without falling out before placing it in the tool holder and tightening the nut. The chuck is spring-loaded; tightening the screw increases clamping strength.
