| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during manual threading, leading to cross-threading. | Always hand-thread the screw initially to feel for smooth engagement. If resistance is met, back it out and re-align. |
| Over-tightening the cap screw, which can strip threads or compromise material integrity. | Employ a calibrated torque wrench and adhere to the recommended torque specifications for the specific application and materials being joined. |
