| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force, leading to thread stripping or fastener breakage. | Consult torque charts or engineering specifications for the correct tightening torque and use a calibrated torque wrench. |
| Using the wrong size wrench, resulting in head damage or inability to achieve proper torque. | Always use a correctly sized hex socket or wrench that fits snugly on the head to prevent slippage and damage. |
