| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using standard stainless steel (e.g., 304) in highly corrosive environments. | Always specify 316 stainless steel for superior corrosion resistance in marine, chemical, or saline conditions. |
| Overtightening the fastener, leading to thread stripping or material deformation. | Consult torque specifications for the specific application and materials being joined to prevent damage. |
