| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening, leading to thread stripping or fastener fracture in aluminum. | Adhere to manufacturer-recommended torque specifications for Aluminum 6061 fasteners. Use a torque wrench for accuracy. |
| Using the wrong size drive tool, which can damage the hex head or lead to improper torque application. | Confirm the correct drive tool size (e.g., 17mm socket for a 24mm hex width) before installation. |
