| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-torquing the fastener, leading to thread stripping or material fatigue. | Always use a calibrated torque wrench and adhere to recommended torque specifications for the specific application and materials being joined. |
| Using the wrong size or type of tool for tightening, which can damage the head and prevent proper torque application. | Utilize the correct size and type of wrench or socket that fully engages with the hex head to ensure even pressure and prevent slippage. |
