| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread stripping or component damage. | Use a torque wrench set to the manufacturer's recommended specification for the mating component and screw size. |
| Using a non-standard or worn tool, which can damage the hex head and compromise torque application. | Always use a correctly sized, high-quality socket or spanner that fits snugly onto the hex head. |
