| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-torquing aluminum fasteners, which can lead to thread stripping or fastener deformation. | Always use a calibrated torque wrench and adhere to recommended torque specifications for aluminum alloys, accounting for thread pitch and mating material. |
| Using steel fasteners in corrosive environments where aluminum would be more suitable, leading to premature corrosion and joint failure. | Select fasteners made of materials appropriate for the operating environment. Aluminum 6061 is an excellent choice for its inherent corrosion resistance. |
