| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a standard steel fastener in corrosive environments. | Always specify 316 stainless steel for applications exposed to moisture, saltwater, or chemicals to prevent premature corrosion and failure. |
| Over-tightening the fastener, leading to thread stripping or head damage. | Utilize a torque wrench and adhere to recommended torque values for M5 fasteners to ensure optimal clamping force without damaging the components. |
