| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to cam-out and damaged fastener head. | Always use a wrench or socket that precisely fits the 20mm hex head for optimal engagement and torque application. |
| Overtightening, which can strip threads or compromise material integrity. | Adhere to torque specifications for the application; hand-tighten and then apply a controlled amount of additional torque. |
