ANCO®PN-LOC®: The Original Structural Locknut

The ANCO® PN-LOC® Structural Locknut is a proprietary, all-metal, self-locking nut renowned for its robust design and exceptional performance in structural applications. This locknut features a patented, non-breakable stainless steel ratchet pin coupled with a unique controlled-lock indentation, ensuring consistent locking torque while minimizing damage to bolt threads and preserving the galvanized surface.

Applications

The ANCO® PN-LOC® locknut is engineered to provide a secure, vibration-resistant fastening solution, crucial in environments where joint integrity is paramount. Its design effectively prevents loosening under dynamic loads, thereby enhancing the safety and reliability of structural assemblies. The coupling of the ratchet pin with the indentation limits damage to bolt threads and reduces the removal of the galvanized surface, ensuring consistent locking torque.

The ANCO® PN-LOC® locknut is widely utilized in various industries, including:

  • Construction: Securing structural components in buildings and infrastructure projects.
  • Transportation: Fastening parts in vehicles, including trucks, trailers, and railcars.
  • Heavy Machinery: Ensuring the integrity of assemblies in industrial equipment and machinery.
  • Marine: Providing reliable fastening solutions in shipbuilding and offshore structures.
