| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench. | Always use a wrench that properly fits the 8mm hex head to prevent stripping. |
| Over-tightening the screw, leading to thread damage or material fatigue. | Consult torque charts for the specific application and materials being joined, and use a calibrated torque wrench. |
| Failing to clean mating threads before installation. | Dirt, debris, or old thread sealant can compromise the connection and lead to premature failure. |
