| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect torque, leading to fastener failure or damage to mating components. | Always consult torque charts specific to the material grade, thread size, and application requirements. Utilize a calibrated torque wrench for accurate tightening. |
| Cross-threading the screw, causing damage to both the screw and the threaded hole. | Initiate tightening by hand to feel the threads engage smoothly. If resistance is met immediately, back out and re-align the screw. |
