| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a wrench that does not fully engage the hex head. | Always use a properly sized socket or wrench that fits snugly to prevent cam-out and damage to the fastener head. |
| Cross-threading the cap screw during installation. | Start threading the cap screw by hand for at least two full turns to ensure it is properly aligned with the mating threads before applying any tools. |
