Coating system revolutionizes corrosion resistance

INF3013™ is engineered to provide superior corrosion resistance and assembly performance over black bolts or mechanically galvanized coatings.

This innovative coating system ensures long-term performance and reliability in demanding environments, making it ideal for critical applications.


  • Versatile coating for F1852 (A325) and exclusive option for F2280 (A490), exceeding ASTM F3125-22.
  • It offers standard shear wrench socket fit, higher nut proof loads, and post-tapping nut coating.
  • Lubrication ensures consistent frictional properties, unlike wax or oil.
  • Structurally sound, resistant to hydrogen embrittlement.
  • Enhances aesthetics and protection with paint application.

INF3013™ sets the benchmark for coating excellence, ensuring unparalleled durability and protection and is available in our tension control and heavy hex head structural bolts.
