Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to stripped hex heads.Always use a wrench that precisely fits the 12mm hex head to ensure proper torque application and prevent damage.
Over-tightening, which can lead to thread stripping or fastener failure.Adhere to the specified torque values for the material and application to avoid overstressing the fastener and the mating components.

Common Applications

  • Heavy machinery assembly
  • Structural steel connections
  • Automotive manufacturing and repair

⚠️ Engineering Warnings

  • Ensure the chosen torque specification is appropriate for the connected materials to prevent damage.
  • Use appropriate personal protective equipment (PPE) when handling and installing fasteners.
