Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to head damage.Utilize a wrench or socket that precisely matches the 13mm head width.
Cross-threading due to improper alignment when starting the screw.Carefully align the screw with the mating threads and hand-tighten a few turns to ensure proper engagement before applying torque.

Common Applications

  • Marine and offshore equipment assembly
  • Chemical processing plant construction
  • Outdoor structural steel fabrication

⚠️ Engineering Warnings

  • Avoid use in environments with high concentrations of chlorides or strong acids without proper risk assessment.
  • Ensure mating components are compatible with 304 stainless steel to prevent galvanic corrosion.
