Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to cam-out and damaged fastener head.Always use a wrench or socket that precisely matches the 10mm head width.
Cross-threading the screw by forcing it into the mating part.Start threading by hand to ensure proper alignment before applying torque.
Over-tightening, which can lead to thread stripping or fastener failure.Tighten until snug and secure. For critical applications, use a torque wrench set to the recommended value.

Common Applications

  • Marine and offshore equipment
  • Chemical processing plants
  • Food and beverage machinery
  • Outdoor structural assemblies
  • Automotive and aerospace components

⚠️ Engineering Warnings

  • Ensure material compatibility with the mating components to prevent galvanic corrosion.
  • Handle with care to avoid scratches or damage to the passivation layer of the stainless steel, which can compromise corrosion resistance.
