| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to stripped hex heads. | Always use the correct size wrench or socket that fits snugly on the hex head. |
| Over-torquing, which can damage threads or the workpiece. | Adhere to recommended torque values and use a calibrated torque wrench for precise tension. |
| Applying lubricant to stainless steel fasteners without verifying compatibility, which can lead to galling. | Use lubricants specifically designed for stainless steel or consult fastener material compatibility charts. |
