📊 Technical Specifications

🛠️ Usage Instructions (Pro-Tip)

1. Secure: Use the slotted end of the tool to clamp the disc nail (chainring bolt) and prevent it from rotating.
2. Apply Force: Use a separate 5mm hexagon wrench on the other side to loosen or tighten the bolt.
3. Safety First: Do not use this tool itself to apply heavy torque—it is designed to act as a fixed/holding function to prevent rotation. Using it to force the bolt might damage the teeth.
