Wichard Captive Pin Twisted Shackle - Diameter 5mm - 3/16"

The Wichard Captive Pin Twisted Shackle in 5mm diameter (3/16 inch) is a premium stainless steel fastening solution designed for serious mariners, commercial fishermen, and boaters who demand reliability in demanding saltwater environments. This compact shackle serves as a critical connection point for rigging, anchor systems, and cargo securing—applications where a single failure means lost equipment or worse.

Built by Wichard Marine, a French manufacturer with decades of marine hardware expertise, this shackle combines traditional twisted pin design with modern captive-pin safety engineering to eliminate the risk of accidental pin loss while underway. The permanently secured pin mechanism ensures that once installed, it cannot vibrate loose or fall out due to wave action or engine vibration, a common problem with conventional shackles in rough seas.

This shackle excels in applications where traditional pin shackles may fail, making it ideal for medium-duty applications, including dinghy launching, deck rigging, and anchor bridle systems on boats between 25 and 50 feet. Stainless steel construction resists rust and corrosion in both freshwater and saltwater conditions, ensuring the shackle maintains integrity season after season with minimal maintenance.
