Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-torquing the aluminum screw, leading to thread stripping or deformation.Always use a calibrated torque wrench and adhere to recommended torque specifications for Aluminum 6061 fasteners.
Using the wrong tool size, which can damage the hex head and impede proper tightening.Utilize a correctly sized socket or wrench that fits the 25mm head width precisely.

Common Applications

  • Aerospace structural components
  • Marine hardware and fittings
  • Lightweight machinery assemblies

⚠️ Engineering Warnings

  • Aluminum 6061 has a lower tensile strength than steel; do not use in applications requiring extreme load-bearing capacity without proper engineering analysis.
  • Galvanic corrosion can occur if dissimilar metals are in direct contact in a corrosive environment; consider isolation methods.
