Wichard Self-Locking Allen Head Pin D Shackle - 12mm Diameter - 15/32"

The Wichard Self-Locking Allen Head Pin D Shackle in 12mm diameter (15/32") is a marine-grade rigging component engineered for serious boaters and commercial fishing operations where gear security and reliability are non-negotiable. Built by Wichard Marine—a name trusted across global maritime industries—this self-locking shackle eliminates the risk of accidental pin disengagement that can occur during rough seas, extended towing, or heavy load applications. Whether you're securing anchor lines, rigging deck equipment, or connecting critical load-bearing hardware, this shackle delivers the dependability that separates safe operations from costly failures.

Forged from grade 316L stainless steel, this shackle resists corrosion and salt-water degradation far longer than standard hardware, ensuring years of service in harsh marine environments. The self-locking mechanism works by seating the allen head pin into one of the machined indentations on the shackle body—a proven French design that requires no secondary fasteners, safety wires, or constant monitoring. The pin head sits flush and secure, preventing snagging on rigging or crew clothing while maintaining absolute load integrity under dynamic stress. At 12mm diameter with the pin's unique allen head geometry, this shackle balances maximum working strength with practical handling for single and double-line configurations common in fishing, anchoring, and deck rigging applications.

Commercial anglers, charter boat operators, and offshore enthusiasts will find this shackle ideal for permanent rigging, mooring systems, and equipment that demands constant reliability without maintenance checks. The 15/32" pin diameter fits standard marine eye loops, clevis fittings, and deck hardware commonly found on vessels ranging from 25-foot center consoles to larger working boats. Installation is straightforward: insert the pin fully into the D-shaped opening, then rotate until the pin head seats securely in an indentation—no tools required beyond an allen wrench for future removal. This shackle meets international maritime standards and performs equally well in freshwater and saltwater conditions, making it a versatile choice for anglers who fish multiple waters or operate in variable climates.
