| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an under-sized wrench, leading to stripped hex head corners. | Always use the correct size socket or wrench that fully engages all six flats of the hex head. |
| Over-tightening, potentially causing thread damage or fastener failure. | Adhere to manufacturer-specified torque values or consult engineering guidelines for the specific application to avoid over-stressing the fastener. |
