| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a standard carbon steel fastener in a corrosive environment. | Always specify 316 stainless steel for applications exposed to saltwater, chemicals, or high humidity to prevent premature corrosion and failure. |
| Over-tightening the fastener, stripping threads or deforming the component. | Refer to torque charts for the specific M17 thread size and material grade, and use a calibrated torque wrench for accurate application. |
