Wichard Self-Locking Allen Head Pin Bow Shackle - 6mm Diameter - 1/4"

The Wichard Self-Locking Allen Head Pin Bow Shackle in 6mm diameter is a marine-grade hardware essential for any serious boater, angler, or sailor who demands reliability at sea. Built for deck rigging, anchor systems, and towing applications, this self-locking shackle eliminates the risk of accidental pin release—a critical safety feature when operating in rough conditions or heavy weather. Whether you're securing fenders, anchoring offshore, or connecting tow bridles, this shackle provides the fail-safe connection your vessel deserves.

Manufactured from marine-grade 316L stainless steel, the Wichard shackle resists corrosion in saltwater environments and maintains its strength even after years of exposure. The self-locking mechanism works by twisting the pin into one of the shackle's indentations, where it locks securely without requiring secondary fasteners or cotter pins. The Allen head design allows you to control pin tension precisely and verify the lock visually—no guesswork required. The 6mm diameter (1/4-inch) sizing strikes the ideal balance between load capacity and ease of handling on deck, making it versatile enough for mid-range rigging while remaining compact enough for confined spaces.

Experienced offshore anglers and boat maintenance professionals favor this shackle for its proven durability and simplicity. It integrates seamlessly with standard marine hardware and requires no special tools beyond a basic Allen wrench for installation and inspection. The self-locking feature is particularly valuable in applications where vibration or constant motion could loosen traditional pinned shackles—critical when fighting the elements or towing under load. For anyone who values peace of mind and dependable deck hardware, the Wichard Self-Locking Allen Head Pin Bow Shackle represents a wise investment in vessel safety and operational integrity.
