| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a wrench that is too large or too small for the hex head. | Always use a properly sized socket or wrench that fits snugly to avoid stripping the hex head. |
| Overtightening the screw, leading to thread stripping or material fatigue. | Utilize a torque wrench to apply the recommended torque specification for the application, ensuring secure fastening without overstressing the threads. |
