| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force without proper torque wrench, leading to thread stripping. | Utilize a calibrated torque wrench to adhere to the recommended torque values for M5 fasteners, preventing damage to both the screw and the mating component. |
| Employing non-compatible tools, resulting in hex head damage. | Always use a correctly sized hex (Allen) wrench or socket that fits snugly into the screw's drive recess to avoid cam-out and stripping. |
