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 matches the 32mm head width of the cap screw.
Over-tightening, causing thread damage or material fatigue.Adhere to the recommended torque specifications for the specific application and materials being joined.
Not cleaning mating threads, resulting in galling or improper seating.Thoroughly clean both the cap screw threads and the receiving threads before installation.

Common Applications

  • Marine hardware and shipbuilding
  • Chemical processing equipment
  • Food and beverage production machinery
  • Outdoor structural components

⚠️ Engineering Warnings

  • Ensure compatibility with mating materials to prevent galvanic corrosion.
  • Consult engineering specifications or a qualified engineer for precise torque requirements.
