| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a standard steel screw in a corrosive environment, leading to premature rust and failure. | Always select fasteners made from materials like Aluminum 6061, stainless steel, or other corrosion-resistant alloys when assembling in environments exposed to moisture or chemicals. |
| Over-tightening the aluminum screw, which can strip the threads or deform the mating material. | Utilize a torque wrench and consult engineering specifications for the correct tightening torque for Aluminum 6061 fasteners to ensure secure fastening without damage. |
