Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an undersized or oversized wrench, leading to fastener head damage or inadequate tightening.Always use a wrench that precisely fits the 26mm head width to ensure proper engagement and prevent stripping.
Over-tightening, which can lead to thread stripping, fastener failure, or deformation of mating components.Adhere to the recommended torque specifications for the M16 size and carbon steel material to prevent over-stressing the fastener.

Common Applications

  • Heavy machinery assembly
  • Structural steel connections
  • Bridge construction

⚠️ Engineering Warnings

  • Carbon steel is susceptible to rust and corrosion in moist or corrosive environments; consider protective coatings or alternative materials if necessary.
  • Ensure proper torque is applied to prevent loosening under vibration or stress.
