| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to cam-out and potential head damage. | Always use a properly sized wrench or socket that fits snugly onto the hex head. |
| Over-tightening the screw, which can strip threads or weaken the fastener. | Adhere to torque specifications recommended for the application and materials involved. A torque wrench is highly recommended. |
| Using in environments where the specific corrosion resistance of 316 stainless steel is not required, leading to unnecessary cost. | Confirm the environmental demands and material compatibility before selecting fasteners. |
