Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size socket, leading to stripping of the hex head.Always verify the socket size matches the hex head dimensions (9mm in this case) before applying torque.
Over-tightening the screw, which can compromise the strength of the mating material or the screw itself.Adhere to the recommended torque specifications for the application. Consult engineering drawings or material datasheets if unsure.

Common Applications

  • Structural assembly in corrosive environments
  • Machinery and equipment manufacturing
  • Marine and offshore installations

⚠️ Engineering Warnings

  • Ensure compatibility of mating materials to prevent galvanic corrosion.
  • Always use appropriate personal protective equipment (PPE) during installation.
