| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size hex wrench, leading to stripped heads or improper torque. | Always select a hex wrench that precisely matches the 19mm head width for secure grip and accurate tightening. |
| Cross-threading the fastener, which can damage both the screw and the mating component. | Start by hand-threading the screw to confirm it’s engaging the threads correctly before applying any tools. |
