Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an undersized wrench, leading to cam-out and potential damage to the hex head.Always use a wrench that fully engages the hex head, ensuring proper torque application and preventing damage.
Cross-threading the screw, which can damage both the screw and the mating threads.Start threading the screw by hand to ensure it is properly aligned before applying any tool torque.

Common Applications

  • Marine hardware and offshore structures
  • Chemical processing equipment
  • Food and beverage processing machinery

⚠️ Engineering Warnings

  • Ensure compatibility with mating materials to prevent galvanic corrosion.
  • Do not exceed recommended torque values, as this can lead to fastener failure or damage to the joined components.
