Wichard Captive Pin Bow Shackle - Diameter 8mm - 5/16"

The Wichard Captive Pin Bow Shackle – Diameter 8mm – 5/16" is a marine-grade fastening component engineered for sailing rigging, deck hardware, and load-bearing applications where reliability is non-negotiable. Designed by Wichard Marine, a leader in precision stainless steel hardware for the marine industry, this shackle serves professional sailors, boat builders, and riggers who demand equipment that withstands saltwater corrosion and repeated dynamic loading. The captive pin design eliminates the risk of accidental pin loss, making it ideal for installations where safety and security cannot be compromised.

This 8mm bow shackle features a captive pin mechanism that remains permanently attached to the shackle body, preventing loss during rigging adjustments or rough seas. The bow design—with its rounded, open loop—provides maximum compatibility with a wide range of fittings, blocks, and deck hardware commonly found on racing and cruising sailboats. Constructed from marine-grade stainless steel, the shackle resists corrosion in salt spray environments and maintains full strength over decades of exposure. The 5/16" diameter specification ensures it meets standard rigging load requirements while fitting into conventional deck fittings and turnbuckle eyes.

Sailors upgrading standing or running rigging, riggers replacing worn hardware, and boat maintenance professionals will find this shackle essential for shrouds, forestays, and auxiliary rigging systems. Its compact dimensions (2 x 2 x 6 inches) and lightweight construction (0.15 lbs) make it easy to carry and install on deck or in tight rigging spaces. Compatibility extends across most modern sailing vessels, from small keelboats to larger cruising yachts, making it a versatile replacement component that meets international marine standards for safety and durability.
