| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread stripping or material deformation. | Use a calibrated torque wrench to adhere to recommended torque specifications for the fastener size and material. |
| Using the wrong tool size, which can damage the hex head and prevent proper tightening or removal. | Always use the correct size socket or wrench that fits snugly onto the hex head. |
