| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening, which can strip threads or deform the clamped components. | Always use a torque wrench set to the manufacturer's recommended torque specification. |
| Using the wrong size wrench, leading to cam-out and potential damage to the hex head. | Select a wrench that precisely fits the 18mm hex head of the cap screw. |
