| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong torque setting, leading to under- or over-tightening. | Consult engineering drawings or torque charts for the correct specification based on the application and mating materials. |
| Cross-threading the cap screw due to misaligned insertion. | Always start threading by hand to ensure proper engagement before applying any tools. |
