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

The Wichard Thimble Shackle with Captive Pin in 8mm (5/16") diameter is a marine-grade rigging hardware component forged from 316L stainless steel. This integrated thimble shackle eliminates the need for a separate thimble when splicing rope, streamlining rigging assembly while maintaining the high working and breaking loads required in demanding saltwater and offshore environments. The captive pin design prevents accidental loss during deployment and recovery operations.

The 8mm diameter accommodates rope up to 12mm, making this shackle suitable for halyard and mainsheet applications where rope load capacity and reliability are non-negotiable. Grade 316L stainless steel offers superior corrosion resistance in salt-air environments compared to standard stainless or galvanized hardware, essential for vessels operating in coastal and offshore conditions. The captive pin mechanism secures the shackle eye without relying on external retention, reducing maintenance points and the risk of hardware failure during rough sea state transitions.

This shackle is specified for sailing vessels, commercial rigging, and marine rescue operations where halyard and mainsheet systems require secure, corrosion-resistant connection points. Operators and riggers working with rope-to-hardware assemblies benefit from the integrated thimble design, which reduces connection points and simplifies inspection routines. The Wichard brand is recognized in the marine industry for precision hardware engineered to ISO and international maritime standards.

The compact design (2 x 1 x 6 inches, weighing 0.45 lbs) integrates easily into existing rigging systems without adding significant weight or bulk to deck assemblies. When replacing worn or corroded shackles, this part offers a direct upgrade path for vessels maintaining 316L-grade hardware standards throughout their rigging architecture.
