Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to cam-out and potential damage to the fastener head.Always use a wrench or socket that precisely fits the 35mm head width of the cap screw to ensure optimal grip and prevent damage.
Over-tightening the screw, which can strip the threads or lead to fastener failure under stress.Adhere to recommended torque values for the specific application and material to prevent over-stressing the screw and mating threads.

Common Applications

  • Machinery assembly and repair
  • Structural steel connections
  • Heavy equipment manufacturing

⚠️ Engineering Warnings

  • Not recommended for highly corrosive environments without appropriate surface treatment.
  • Always verify load capacity and compatibility with mating components before installation.
