| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread stripping or component damage. | Utilize a torque wrench and adhere to the recommended torque specifications for the material and application. |
| Using the wrong size wrench or socket, which can round off the hex head and impede proper tightening. | Always select a wrench or socket that precisely fits the hex head dimensions for optimal engagement and force transfer. |
