| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a socket that is the wrong size for the hex head, leading to slippage and potential damage to the fastener or tool. | Always verify the correct socket size for the M9 hex head, typically 14mm, to ensure a snug fit and optimal torque transfer. |
| Over-tightening the cap screw, which can strip the threads or cause material fatigue, compromising the joint's integrity. | Consult engineering drawings or torque charts for the recommended torque specification and utilize a calibrated torque wrench for precise tightening. |
