Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-torquing aluminum fasteners, which can lead to thread stripping or material deformation.Always consult torque charts specific to the fastener's grade and material, and utilize a calibrated torque wrench.
Using steel fasteners in corrosive environments where aluminum is specified.Select fasteners made from appropriate corrosion-resistant materials like Aluminum 6061 to prevent galvanic corrosion and premature failure.

Common Applications

  • Aerospace structural components
  • Automotive chassis and body applications
  • Marine equipment and fittings

⚠️ Engineering Warnings

  • Aluminum 6061 has lower tensile strength than steel; do not use in applications requiring extreme load-bearing capacity without proper engineering analysis.
  • Avoid direct contact with dissimilar metals in corrosive environments to prevent galvanic corrosion; consider isolation washers or coatings if necessary.
