| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to stripped hex heads and improper torque application. | Always use a correctly sized hex socket or wrench that fits snugly on the hex head to prevent slippage and damage. |
| Over-tightening the screw, which can lead to thread stripping, component deformation, or fastener breakage. | Adhere to the manufacturer's recommended torque specifications or consult engineering drawings for precise tightening values. |
