Wichard Key Pin Shackle - Diameter 8mm - 5/16"

The Wichard Key Pin Shackle — Diameter 8mm — 5/16" is a professional-grade marine fastener trusted by experienced boaters, riggers, and sailors for secure deck hardware connections. This compact yet robust shackle is engineered for applications where quick, reliable attachment and detachment matter: anchor lines, halyard systems, chainplate connections, and rigging adjustments on vessels of all sizes. Built for salt water and freshwater environments alike, it delivers the dependability you need when you're far from shore and conditions demand gear that won't fail.

Forged entirely from marine-grade 316L stainless steel, the Wichard Key Pin Shackle resists corrosion and fatigue that plague standard hardware in saltwater service. The key design—a half-turn pin mechanism—eliminates fumbling with traditional screw pins or toggles, allowing single-handed operation even in rough seas or cold weather. The pin remains captive to the shackle body, eliminating the frustration and safety risk of losing critical hardware overboard. The 8mm diameter provides an optimal balance of strength and weight, suitable for both cruising and performance sailing applications without unnecessary bulk.

Experienced crews value the Wichard Key Pin Shackle for applications requiring frequent adjustments under load or for emergency rigging changes. Its compact 2 x 2 x 6 inch footprint fits standard chainplates and deck eyes without obstruction, while the proven Wichard design ensures compatibility with industry-standard cordage, wire, and hardware terminations. Whether you're cruising coastal waters, racing, or working commercial vessels, this shackle performs reliably across salt and fresh water. Weighing just 0.25 lbs, it won't strain your rigging budget or boat's load calculations, making it an economical upgrade for any marine system requiring secure, quick-release connections.
