Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect torque, leading to under-tightening or over-tightening.Always consult engineering specifications or a torque chart for the recommended tightening torque for M6 fasteners in your specific application.
Cross-threading the screw into the mating component.Start threading the screw by hand to ensure it engages the threads properly before using any tools.

Common Applications

  • Marine hardware and equipment
  • Chemical processing plant construction
  • Food and beverage industry machinery

⚠️ Engineering Warnings

  • Ensure compatibility with mating components; thread pitch and diameter must match.
  • While 316 stainless steel offers excellent corrosion resistance, prolonged exposure to certain aggressive chemicals may still cause degradation. Verify material suitability for your specific chemical environment.
