| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the fastener, leading to thread stripping or fastener fracture. | Utilize a calibrated torque wrench and adhere strictly to recommended torque values for the specific material and thread engagement. |
| Using a fastener with insufficient corrosion resistance for the intended environment. | Always verify the material grade (316 stainless steel in this case) is appropriate for the expected exposure to corrosive elements like saltwater, chemicals, or high humidity. |
