Wichard Self-Locking Twisted Shackle - 10mm Diameter - 13/32"

The Wichard Self-Locking Twisted Shackle in 10mm diameter is a critical piece of deck hardware for any serious angler or boater who demands reliability under extreme conditions. Whether you're anchoring in rough offshore waters, securing rigging on a sailboat, or managing heavy loads on a working vessel, this shackle delivers the fail-safe performance that keeps your gear in place when it matters most. Designed to French marine engineering standards, Wichard shackles have earned their reputation among professional mariners and experienced recreational boaters worldwide.

The self-locking mechanism is the key to this shackle's dependability—the twisted design creates positive mechanical interference that prevents accidental loosening from vibration, wave action, or constant movement. At 10mm diameter, this shackle handles substantial loads without adding unnecessary weight to your rigging system, making it ideal for both small cruising sailboats and larger fishing vessels. The twisted pin geometry also simplifies installation; you simply insert the pin and the geometry locks it in place automatically, eliminating the need for additional safety wire or cotter pins in most applications. The 13/32" dimension provides excellent compatibility with standard marine hardware and cleats.

Experienced boaters and fishing crews rely on Wichard Self-Locking Twisted Shackles for anchor systems, boom gallows, standing rigging terminations, and deck-to-hull connections where security and simplicity matter equally. The self-locking feature is especially valuable in high-vibration environments such as fishing boats with heavy engines or sailboats in rough seas, where traditional shackles may require frequent re-tightening. This 10mm size strikes the perfect balance for mid-range applications without the bulk or expense of oversized hardware, making it a practical choice for vessel owners who refuse to compromise on safety.
