Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive torque on aluminum fasteners.Always refer to torque specifications for aluminum 6061 fasteners to prevent stripping threads or deforming the material.
Not checking for thread contamination before installation.Thoroughly inspect both the screw and mating threads for any dirt, debris, or damage that could compromise the connection.

Common Applications

  • Aerospace structural components
  • Automotive interior and exterior trim
  • Marine hardware and fittings

⚠️ Engineering Warnings

  • Aluminum 6061 has lower tensile strength than steel; ensure suitability for load-bearing applications.
  • Avoid using in environments with strong alkaline or acidic solutions, which can degrade aluminum over time.
