| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a torque value that is too high, leading to thread stripping or fastener breakage. | Consult engineering specifications or a torque chart for the correct torque value based on the material strength and application. |
| Cross-threading the screw by forcing it into misaligned or damaged threads. | Carefully align the screw with the threads and initiate tightening by hand for several turns to ensure proper engagement before using a tool. |
