Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, leading to thread stripping or material deformation.Utilize a calibrated torque wrench and adhere to the recommended torque values for the specific application and mating materials.
Using the wrong size wrench, which can damage the hex head and result in an incomplete connection.Ensure the socket size precisely matches the 20mm hex head width of the cap screw for optimal grip and torque transfer.

Common Applications

  • Structural assembly in corrosive environments
  • Marine and offshore equipment
  • Chemical processing plants

⚠️ Engineering Warnings

  • Ensure compatibility with mating components and thread pitch.
  • Avoid prolonged exposure to environments exceeding the material's corrosion resistance limits without protective measures.
