| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to head damage or improper torque. | Utilize a correctly sized wrench (14mm) to ensure a snug fit and efficient torque application. |
| Overtightening, which can strip threads or compromise the fastener's integrity. | Adhere to the specified torque values for the application to prevent damage and ensure reliable performance. |
| Using in a highly corrosive environment without verifying 316 stainless steel suitability. | Confirm that the specific corrosive agents and concentrations in the environment are within the acceptable limits for 316 stainless steel. |
