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

The Wichard Self-Locking Allen Head Pin D Shackle is a marine-grade connector engineered for serious boaters, riggers, and anglers who demand reliability in demanding saltwater and freshwater environments. This 10mm diameter shackle serves as a critical link in deck hardware, anchor systems, and rigging applications where accidental pin withdrawal could compromise safety or gear positioning. Whether you're securing an anchor bridle, connecting deck fittings, or assembling a complex rigging system, this self-locking design eliminates the need for secondary safety measures and constant visual inspection of pin security.

Manufactured from grade 316L stainless steel, the Wichard Self-Locking Allen Head Pin D Shackle resists corrosion in harsh marine environments where standard fasteners fail within a season. The self-locking mechanism works through indentations in the shackle body that grip the pin head, creating friction-based retention without reducing the shackle's load-bearing capacity. The allen head design allows quick pin removal using standard hex keys, enabling field adjustments and repairs without specialized tools—a practical advantage when you're miles offshore or anchored in remote waters. At 10mm diameter with a 13/32" pin specification, this shackle delivers substantial working load capacity suitable for heavy-duty applications.

Professional captains, charter boat operators, and maintenance-conscious anglers who value uptime and safety choose Wichard hardware for its proven track record in commercial and recreational fleets. This shackle integrates seamlessly into existing marine rigging systems and pairs effectively with other Wichard fittings, cleats, and deck hardware. Installation is straightforward—insert the pin into the shackle body until it seats fully in one of the retention indentations, then tighten with an allen wrench to lock it in place. For anyone upgrading aging stainless steel fittings or building new rigging from the ground up, this self-locking shackle represents a significant reduction in maintenance checks and peace of mind during extended time on the water.
