Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size hex wrench, leading to stripped head or improper torque.Always use the correct size hex wrench (typically 10mm for an M6 screw with a 28mm head) to ensure proper engagement and torque application.
Over-tightening the screw, which can damage the threads or the mating material.Apply torque incrementally and stop once snug, or consult engineering specifications for recommended torque values to avoid material stress or failure.

Common Applications

  • Marine hardware and fittings
  • Outdoor equipment and structures
  • Chemical processing equipment
  • Food processing machinery
  • Automotive and aerospace components

⚠️ Engineering Warnings

  • Ensure compatibility of mating threads to prevent cross-threading and potential fastener failure.
  • For critical load-bearing applications, always verify the tensile strength requirements against the screw's capabilities and apply appropriate torque.
