Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the aluminum screw, which can strip threads or compromise the fastener's integrity.Always adhere to the recommended torque specifications for Aluminum 6061 fasteners, utilizing a torque wrench for accuracy.
Using the wrong size wrench, leading to slippage and potential damage to the hex head.Select a wrench or socket that precisely fits the 34mm head width to ensure a secure grip and efficient tightening.

Common Applications

  • Aerospace structural components
  • Automotive chassis and body assembly
  • Marine hardware and fittings

⚠️ Engineering Warnings

  • Aluminum 6061 has a lower tensile strength compared to steel; do not substitute in applications requiring high load-bearing capacity without engineering review.
