| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread stripping or component damage. | Utilize a torque wrench to adhere to the manufacturer's recommended torque values for the specific application and materials. |
| Using the wrong size wrench, resulting in cam-out and damage to the screw head. | Always select a wrench or socket that fully engages the hex head for optimal grip and force transfer. |
