Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, which can strip the threads in the softer aluminum material.Always use a torque wrench and consult material-specific torque charts to ensure proper tension without damaging the threads.
Using the wrong type of tool, potentially damaging the hex head and compromising torque application.Utilize a correctly sized hex socket or wrench to ensure a snug fit and prevent cam-out.

Common Applications

  • Aerospace component assembly
  • Automotive structural parts
  • Marine equipment fastening

⚠️ Engineering Warnings

  • Aluminum 6061 has lower tensile strength than steel; do not use in applications requiring high clamping force unless specifically engineered.
  • Avoid galvanic corrosion when mating with dissimilar metals; consider isolation or plating if long-term exposure is expected.
