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

The Wichard Captive Pin D Shackle — 8mm diameter (5/16-inch) — is a forged grade 316L stainless steel rigging component engineered for applications requiring secure, vibration-resistant attachment. The captive pin design keeps the pin tethered to the shackle body at all times, eliminating the risk of pin loss during field operations, training, or maritime use. The pin locks positively into one of the integral indentations on the shackle, preventing accidental opening under load or vibration.

Grade 316L stainless steel construction provides superior corrosion resistance in salt air, harsh weather, and chemically aggressive environments — critical for operators working in coastal zones, maritime rescue, or long-term outdoor deployment. The 8mm diameter delivers working loads and breaking strength suitable for standard tactical rigging applications, rescue operations, and load-bearing attachments. The D-shaped design reduces snagging and catches on gear, webbing, and equipment during rapid movement or extraction scenarios.

This shackle is ideal for tactical teams, SAR (search and rescue) personnel, offshore operations, recovery rigging, and any scenario where a secure, corrosion-resistant, non-detachable fastening device is essential. The captive pin eliminates procedural steps needed to track and manage loose pins in high-tempo environments. Operators and riggers trust Wichard Marine components for their precise engineering and reliability under demanding field conditions.

Wichard is an ISO 9001-certified French manufacturer with decades of heritage in marine and tactical rigging hardware. The 8mm captive pin D shackle meets the standards expected in professional rescue, military, and commercial applications where equipment failure is not an option.
