Specification
Information

D shackle body: Heat-treatable steel, die-forged, hot-dip galvanized
Pin: Heat-treatable steel, die-forged, galvanic zinc plated, lacquered finish

Type A: With threaded pin
Type B: With bolt nut and cotter pin

High-strength, GN 584 D shackles are made in accordance with US Federal Specification RR-C-271, and feature six-fold safety standards. This means that the minimum failure load is at least six times greater than the value of the nominal load (WLL).
The rated size and the nominal load (WLL) are drop-forged into the shackle which makes it easier to select the proper sling gear. In general, the nominal load must not be exceeded.
The design with bolt nut and cotter pin (Type B) is normally recommended for permanent connections. The pin is allowed to rotate, and the bolt nut is secured against inadvertent loosening with the cotter pin.
