Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an undersized wrench, leading to fastener head damage and improper torque application.Always use a wrench or socket that precisely matches the 21mm head width of the M23 cap screw to ensure proper engagement and prevent stripping.
Over-tightening the screw, which can lead to thread stripping or material fatigue.Adhere to the recommended torque specifications for the specific application and material being fastened to avoid over-stressing the fastener and mating components.

Common Applications

  • Heavy machinery and equipment assembly
  • Structural steel connections
  • Automotive and aerospace manufacturing

⚠️ Engineering Warnings

  • Ensure compatibility with the mating component's thread size and material.
  • Always wear appropriate personal protective equipment (PPE) during installation and handling.
