Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the aluminum screw, which can strip the threads or deform the component.Always consult a torque chart for Aluminum 6061 and the specific application. Use a calibrated torque wrench.
Using the wrong size wrench, leading to cam-out and damage to the hex head.Verify the wrench size matches the 22mm head width precisely before applying torque.

Common Applications

  • Aerospace components
  • Automotive chassis and body assembly
  • Marine hardware and fixtures
  • Lightweight structural framing
