| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a lower grade stainless steel in corrosive environments. | Always specify 304 or 316 stainless steel for applications exposed to moisture, chemicals, or saltwater to prevent premature corrosion. |
| Over-tightening the fastener, leading to thread stripping or material fatigue. | Refer to torque charts for the specific application and material being joined, and use a calibrated torque wrench for precise tightening. |
