| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening, especially in softer materials, can strip threads or deform the mating surface. | Always use a calibrated torque wrench and adhere to recommended torque values for Aluminum 6061 applications. |
| Using the wrong size wrench or socket can round off the hex head, making removal difficult. | Ensure the correct size socket or wrench is used, fitting snugly onto the hex head. |
