Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a wrench that does not fully engage the hex head, leading to stripping.Always use a properly sized socket or wrench that fits snugly onto the hex head to ensure even torque distribution and prevent damage.
Cross-threading the screw by forcing it into the mating hole.Carefully align the screw with the threads and initiate tightening by hand to ensure proper thread engagement before applying mechanical force.

Common Applications

  • Marine and offshore equipment
  • Chemical processing equipment
  • Food processing machinery
  • Structural steel connections

⚠️ Engineering Warnings

  • Always wear appropriate safety glasses when installing fasteners.
  • Ensure compatibility with mating materials to prevent galvanic corrosion, especially in dissimilar metal assemblies.
