Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the aluminum screw, leading to thread stripping or material deformation.Adhere to recommended torque specifications for Aluminum 6061 fasteners. Use a torque wrench for precise control, especially in critical applications.
Using the wrong tool size for the hex head, which can damage the head and prevent proper tightening.Always use a hex wrench or driver that precisely matches the 10mm head width to ensure secure engagement and prevent cam-out.

Common Applications

  • Aerospace structural components
  • Automotive interior and exterior trim
  • Marine hardware and fittings
  • Electronic enclosure assembly
  • Lightweight machinery and equipment

⚠️ Engineering Warnings

  • Aluminum 6061 has a lower tensile strength than steel; do not exceed its load-bearing capacity.
  • Avoid using in highly abrasive environments or where significant impact loads are expected without proper design considerations.
