| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the fastener, which can strip the threads in the mating material or the fastener itself due to Aluminum's lower tensile strength compared to steel. | Utilize a torque wrench and adhere to the specified torque values for Aluminum 6061 fasteners. Refer to engineering standards or material supplier recommendations for precise figures. |
| Using excessive force or improper tools, potentially damaging the hex head or the mating surface. | Employ the correct size socket wrench or hex bit that fits snugly. Apply steady, controlled pressure during tightening. |
