Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the aluminum screw, which can strip the threads or deform the material.Always use a torque wrench and adhere to the recommended torque specifications for Aluminum 6061 fasteners.
Using incompatible washers or nuts that may cause galvanic corrosion with the aluminum screw.Ensure all mating components are either aluminum or compatible materials to prevent galvanic corrosion.

Common Applications

  • Aerospace structural components
  • Marine hardware and fittings
  • Lightweight automotive assemblies
  • Industrial machinery frames

⚠️ Engineering Warnings

  • Aluminum 6061 has a lower tensile strength than many steel alloys; ensure it meets the load-bearing requirements of your application.
  • Avoid use in environments with extreme temperatures or aggressive chemicals that may degrade aluminum alloy properties.
