Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force, leading to thread stripping or material deformation.Apply recommended torque specifications for M7 fasteners in Aluminum 6061. Utilize a torque wrench for accuracy.
Cross-threading the screw by forcing it into the receiving material.Start threading by hand to ensure proper alignment before using a tool. If resistance is met, back out and re-align.

Common Applications

  • Aerospace component assembly
  • Automotive chassis and body fastening
  • Marine hardware and structural connections

⚠️ Engineering Warnings
