| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to cam-out and stripped hex heads. | Always use a correctly sized hex wrench or socket that fits snugly into the hex head to ensure maximum torque transfer and prevent damage. |
| Over-tightening the screw, which can lead to thread damage or fastener failure. | Adhere to the manufacturer's recommended torque specifications for the specific application and materials being joined. Use a torque wrench for accuracy. |
