Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the aluminum screw, leading to stripped threads or reduced fatigue life.Use a calibrated torque wrench and adhere to manufacturer-recommended torque specifications for M22 threads in Aluminum 6061.
Using inappropriate tools that can damage the hex head or the workpiece surface.Employ a properly sized, high-quality hex socket that fits snugly to ensure even force distribution and prevent cam-out.

Common Applications

  • Structural framework assembly in marine environments
  • Lightweight component attachment in aerospace applications
  • Corrosion-resistant bolting for outdoor equipment and signage

⚠️ Engineering Warnings

  • Aluminum 6061 has lower tensile strength than steel; select fasteners appropriate for the load requirements.
  • While corrosion-resistant, prolonged exposure to aggressive chemicals may degrade the material; consult compatibility charts.
