Wichard HR Long D Shackle - 10mm Diameter - 25/64"

The Wichard HR Long D Shackle – 10mm Diameter – 25/64" is a premium-grade stainless steel fastener engineered for serious marine applications where reliability under load is non-negotiable. Built for anchoring systems, rigging, and heavy-duty deck hardware on vessels ranging from commercial fishing boats to offshore cruisers, this shackle delivers the strength and corrosion resistance demanded by professionals who spend their lives on the water. Whether you're securing ground tackle, connecting heavy line, or assembling critical rigging components, this long D-shackle offers the dimensional clearance and mechanical advantage that experienced boaters rely on.

Forged from HR stainless steel (17-4 PH precipitation-hardened alloy), the Wichard HR Long D Shackle achieves working and breaking loads that can exceed standard 316L stainless by up to 60 percent—a significant advantage when anchoring in heavy weather or managing dynamic rigging loads. The long D profile provides ample clearance for soft shackles, multiple wraps of line, or integration with connector chains, while the 10mm diameter strikes a balance between strength and weight, critical for vessels where every pound matters. The precipitation-hardened 17-4 PH alloy resists corrosion in saltwater environments without sacrificing the toughness required for shock loads inherent in seagoing conditions.

This shackle suits cruising sailors, charter operators, commercial fishing crews, and any boater upgrading ground tackle or deck systems to meet higher safety margins. The 25/64" opening accommodates standard marine hardware and is compatible with anchor chain, swivels, and heavy-duty stainless eye bolts common in marine rigging. Installation is straightforward—simply insert the pin perpendicular to the bow, secure with a cotter pin or cable tie, and verify the load path is aligned. For those who understand that anchoring and rigging failures happen at sea when conditions are worst, the Wichard HR Long D Shackle represents a deliberate investment in gear that holds when it matters most.
