Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the aluminum screw, which can strip the threads or deform the mating material.Always adhere to torque specifications provided by the design engineer or by consulting industry standards for the specific material combination.
Using the wrong size or thread pitch of screw, leading to a loose or unusable joint.Verify the screw's M5 thread size and pitch against the requirements of the mating component before installation.

Common Applications

  • Lightweight structural assemblies in aerospace and automotive.
  • Corrosion-resistant fixtures in marine and outdoor environments.
  • Enclosures and mounting brackets for electronic equipment.

⚠️ Engineering Warnings

  • Aluminum 6061 has lower tensile strength than steel; do not use in applications requiring high clamping forces unless specifically designed for.
  • Avoid galvanic corrosion when mating with dissimilar metals; consider insulating washers or coatings if necessary.
