| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a standard stainless steel (e.g., 18-8) in highly corrosive environments. | Always select 316 stainless steel for superior resistance to chlorides and acids in marine, chemical, or food processing applications. |
| Over-tightening the cap screw, leading to thread stripping or fastener failure. | Adhere to the recommended torque specifications for the fastener size and material to prevent damage and ensure proper joint integrity. |
