| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size hex driver, leading to cam-out and potential damage to the fastener head. | Always use a hex driver that precisely matches the 8mm head width of the cap screw for optimal torque transfer and to prevent damage. |
| Cross-threading the fastener during installation, causing damage to both the screw and the mating threads. | Start threading the cap screw by hand to ensure it is properly aligned before applying any torque. If resistance is met, back it out and try again. |
