Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to stripped hex heads.Always use a properly sized 34mm hex wrench or socket for tightening and loosening.
Cross-threading the screw, damaging both the screw and the receiving threads.Carefully align the screw with the threads and hand-tighten for at least two full turns before applying any significant torque.
Overtightening, which can lead to thread stripping or material deformation.Tighten to the recommended torque specification for the application and materials being joined.

Common Applications

  • Structural steel assembly
  • Marine and offshore equipment
  • Food processing machinery
  • Chemical plant construction
  • Outdoor infrastructure projects

⚠️ Engineering Warnings

  • Ensure mating threads are clean and free from debris before installation.
  • Do not exceed the recommended torque limits for the application to prevent damage.
