Wichard Self-Locking Allen Head Pin Bow Shackle - 10mm Diameter - 13/32"

The Wichard Self-Locking Allen Head Pin Bow Shackle in 10mm diameter is a professional-grade marine fastener designed for serious boaters and offshore fishermen who demand reliability in extreme conditions. Built by Wichard Marine, a trusted name in French marine hardware, this shackle serves as a critical connection point for anchors, tow systems, and rigging applications where sudden loads and corrosive saltwater environments demand zero tolerance for failure.

The self-locking mechanism eliminates the risk of accidental pin removal—a failure mode that could cost you your anchor or worse on the water. The 10mm diameter construction provides substantial holding power while maintaining manageable weight for deck operations and manual handling. The self-locking allen head pin design incorporates a friction-lock mechanism that prevents vibration-induced loosening, a common problem with standard pins exposed to engine vibration and wave action.

This shackle excels in anchor systems, where its bow configuration—with its open rounded top—allows quick attachment and detachment of chain, rope, or cable without requiring complete disassembly. This feature is critical when working solo or in rough seas where every second counts. The stainless steel construction resists rust and galvanic corrosion, ensuring years of service in saltwater and brackish environments without maintenance.
