| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using standard stainless steel (e.g., 304) in highly corrosive environments. | Always specify 316 stainless steel for marine, chemical, or high-salinity applications to prevent premature corrosion and failure. |
| Over-tightening or under-tightening the screw, leading to thread damage or insufficient clamping force. | Utilize a calibrated torque wrench and consult engineering drawings or application-specific torque charts to achieve the correct tension. |
