| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using standard stainless steel in highly corrosive environments. | Always select 316 stainless steel for applications involving chlorides, strong acids, or saltwater exposure to prevent premature corrosion. |
| Over-tightening the screw, leading to thread damage or material fatigue. | Utilize a torque wrench and adhere to recommended torque values to prevent over-stressing the fastener and mating components. |
