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

The Wichard Self-Locking Allen Head Pin Bow Shackle is a marine-grade rigging component engineered for vessels requiring secure, corrosion-resistant anchor and mooring connections. Built by Wichard Marine—a trusted name among professional and recreational boaters—this 12mm diameter shackle delivers the reliability needed on saltwater and freshwater applications where equipment failure is not an option. Whether securing fenders, anchor systems, or deck hardware, this shackle provides the locking integrity that keeps gear in place through rough seas and constant motion.

Forged from 316L stainless steel, the shackle features a self-locking twisted design with an allen head pin that sits firmly in one of the integrated indentations, eliminating the need for secondary locking mechanisms like cotter pins or safety wires. The allen head design allows for tool-assisted engagement and removal, critical when working in confined spaces or wearing gloves on deck. The 12mm (15/32") diameter provides substantial strength for heavy-load applications while remaining compact enough for space-conscious installations. This self-locking geometry resists vibration-induced loosening, a common failure mode in standard pin shackles exposed to engine vibration and wave action.

Boaters managing deck hardware, anchor systems, and mooring configurations benefit most from this shackle's reliability and minimal maintenance profile. The 316L stainless steel construction ensures long-term corrosion resistance in salt spray environments, extending service life and reducing replacement cycles. At 1 lb, the shackle is lightweight enough for rigging applications yet substantial enough to handle the cyclic loading seen in anchoring, towing, and tie-down scenarios. Installation is straightforward—simply insert the allen head pin into the twist-locking indentation and tighten with an allen wrench until seated; no additional hardware required.
