Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to head stripping.Always use a wrench or socket that precisely fits the 36mm hex head to prevent damage.
Cross-threading the M15 screw, damaging the threads of both the screw and the mating component.Start threading by hand to ensure proper alignment before applying any tool.
Over-tightening, which can lead to material fatigue or thread deformation.Use a calibrated torque wrench and adhere to recommended torque specifications for the M15 thread size and material.

Common Applications

  • Marine hardware and structural components
  • Chemical processing equipment
  • Outdoor architectural and infrastructure projects
  • Heavy machinery and industrial assembly

⚠️ Engineering Warnings

  • Ensure proper torque is applied to avoid fastener failure.
  • Verify compatibility of mating threads to prevent cross-threading damage.
  • While 304 stainless steel offers excellent corrosion resistance, it is not impervious to all chemicals; consult material compatibility charts for specific applications.
