Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to stripped bolt heads or improper torque.Always use a wrench or socket that precisely matches the head width (30mm) of the cap screw.
Over-tightening the fastener, which can lead to thread stripping or material deformation, especially in aluminum.Adhere to the manufacturer's specified torque values for M9 fasteners in Aluminum 6061 to avoid damage.

Common Applications

  • Aerospace and Automotive Component Assembly
  • Marine Hardware and Fixtures
  • Structural Frameworks in Corrosive Environments

⚠️ Engineering Warnings

  • Aluminum 6061 has good strength but is not suitable for applications requiring extremely high tensile loads that could exceed its yield strength.
  • Avoid using aggressive cleaning agents or abrasive materials that could damage the corrosion-resistant surface of the Aluminum 6061.
