Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening, leading to thread stripping or fastener fracture.Always use a torque wrench and adhere to manufacturer-specified torque values for the application.
Using an incorrect tool size, which can damage the hex head and hinder proper tightening.Verify the tool size matches the hex head width (10mm) before applying torque.

Common Applications

  • Machinery and Equipment Assembly
  • Structural Support Systems
  • General Industrial Fabrication

⚠️ Engineering Warnings

  • Ensure the carbon steel material is suitable for the operating environment to prevent corrosion if exposed to moisture or corrosive substances.
  • Verify that the thread pitch and diameter of the cap screw are compatible with the mating component.
