Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an undersized or oversized wrench, leading to head damage or slippage.Always use a wrench or socket that precisely fits the 36mm hex head to ensure proper torque transfer and prevent damage.
Over-tightening the screw, which can strip threads or compromise material integrity.Adhere to specified torque values for the application to prevent over-stressing the fastener and its mating components.

Common Applications

  • Heavy machinery assembly
  • Structural steel fabrication
  • Automotive chassis and engine components

⚠️ Engineering Warnings

  • Ensure compatibility with mating thread pitch and material before installation.
  • Use appropriate personal protective equipment (PPE) during handling and installation.
