| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an improperly sized wrench, leading to stripped hex heads. | Always use a correctly sized metric wrench that fits snugly to apply torque effectively and prevent damage to the fastener head. |
| Over-tightening or under-tightening, compromising joint integrity. | Utilize a calibrated torque wrench to achieve the recommended torque specifications for the specific application and material being joined. |
