Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to stripping of the hex head.Always use a wrench or socket that precisely matches the 31mm head width for optimal engagement and torque transfer.
Applying excessive torque, which can damage the threads or the mating component.Tighten to the recommended torque specification for the application, considering the material strength of both the screw and the fastened components.

Common Applications

  • Marine hardware and equipment assembly
  • Food processing machinery
  • Chemical processing plants
  • Outdoor structural components

⚠️ Engineering Warnings

  • Ensure the mating threads are clean and free of debris to prevent galling or cross-threading.
  • For critical applications, consider using a thread-locking compound to prevent loosening under vibration.
