| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench or socket, leading to stripped hex heads. | Always use the correct size socket or wrench that fits snugly on the hex head to prevent damage and ensure proper torque application. |
| Over-tightening the screw, which can lead to thread damage or fastener failure. | Adhere to recommended torque specifications for the application to avoid over-stressing the fastener and the mating components. |
