Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the aluminum screw, which can strip threads or deform the material.Utilize a torque wrench set to the manufacturer's recommended torque specification for M9 aluminum fasteners.
Using the wrong size wrench, leading to cam-out and damage to the hex head.Ensure the wrench size precisely matches the 35mm head width of the cap screw.

Common Applications

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

⚠️ Engineering Warnings

  • Aluminum 6061 has lower tensile strength than steel; do not exceed design load limits.
  • Avoid using in high-temperature environments where aluminum alloy properties may degrade.
