| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to head stripping. | Always use a wrench or socket that precisely fits the 17mm hex head to prevent damage and ensure proper torque application. |
| Cross-threading during initial engagement. | Carefully align the cap screw with the tapped hole or nut and initiate threading by hand for several turns to confirm proper engagement before applying any tool. |
