| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-torquing the fastener, leading to thread stripping or material deformation. | Always use a calibrated torque wrench and adhere to specified torque values for Aluminum 6061 fasteners. |
| Using the wrong tool size for the hex head, resulting in cam-out and potential damage to the fastener head. | Utilize the correct size hex socket or wrench that precisely fits the head dimensions (35mm width in this case). |
