| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during initial threading, leading to cross-threading. | Always hand-thread the screw for at least two full rotations before applying any tools to confirm proper thread alignment. |
| Overtightening the screw, which can strip threads or compromise material integrity. | Refer to a torque chart for the specific application and material, and use a calibrated torque wrench. |
