| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an improperly sized wrench, leading to head stripping. | Always use a wrench or socket that precisely fits the 15mm hex head to prevent damage and ensure proper torque application. |
| Over-tightening, which can strip threads or compromise the fastener's integrity. | Adhere to the specified torque values for the application to avoid over-stressing the screw and its mating components. |
