Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening, which can strip the M4 threads or deform the Aluminum 6061.Utilize a torque wrench and adhere to recommended torque values for M4 fasteners in Aluminum 6061.
Using a driver size that does not precisely match the 15mm hex head width, leading to cam-out and potential damage.Ensure the hex driver or wrench is the correct size for the 15mm head width to achieve a secure grip.

Common Applications

  • Aerospace structural components
  • Marine equipment and fittings
  • Lightweight automotive assemblies

⚠️ Engineering Warnings

  • Aluminum 6061 has lower tensile strength than steel; ensure load requirements are met.
  • Avoid use in extreme temperature or highly abrasive environments without proper consideration.
