Palnut Type Lock Nut | Mechanically galvanized | Poleline Hardware

Palnut Type Lock Nut | Mechanically Galvanized | Poleline Hardware Reliable Spring-Tension Locking for Poleline Hardware. The Yokelink Palnut Type Locknut is an engineered, lightweight secondary fastener designed to prevent the primary load-bearing nuts from loosening due to high vibration, wind loads, or hardware shrinkage on utility poles. How the Spring Action Works: Stamped from high-quality AISI 1050 Spring Steel, the Palnut is installed on top of a standard square or hex nut. When tightened with a wrench, the Palnut distorts slightly, creating a powerful, spring-like prevailing torque that grips the bolt threads and firmly presses against the primary nut. When the load is released, it returns to its original shape. To maintain the integrity of the spring steel and ensure precise thread engagement, our Palnut type locknuts are Mechanically Galvanized to ASTM B695 Class 50, providing excellent corrosion resistance without the hydrogen embrittlement risks associated with standard h…
