The Green Pin Super® Bow Shackle FN is a grade 8 bow shackle featuring a safety bolt and fixed nut. It offers easier handling due to its smaller size and weight while maintaining equal Working Load Limit (WLL) compared to non-Super products. Ideal for dynamic loads or extreme vibrations, it has a triple safety mechanism (split pin, safety bolt, and fixed nut). The fixed nut is securely attached to the pin head with bolts and Nord-Lock® washers. Galvanization ensures long-term durability, and the shackle minimizes wear and tear on counter components like wire ropes by hiding the screw thread within its eye chamber.
