| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread stripping or component damage. | Always use a calibrated torque wrench and consult manufacturer specifications for the correct torque value. |
| Using the wrong tool size for the 31mm hex head, causing damage to the fastener head. | Utilize a correctly sized socket or wrench specifically designed for M20 hex heads. |
| Installing in corrosive environments without confirming material compatibility, leading to premature failure. | Verify that the 316 stainless steel grade is suitable for the specific chemical or environmental exposure. |
