Wichard Self-Locking D Shackle - Diameter 5mm - 3/16"

The Wichard Self-Locking D Shackle in 5mm diameter (3/16") is a grade 316L stainless steel rigging component engineered for mission-critical load applications where vibration-induced loosening cannot be tolerated. The self-locking pin mechanism seats into precision-machined indentations on the shackle body, eliminating the risk of accidental disengagement under dynamic conditions—a critical safety feature in high-vibration environments common to maritime operations, tactical vehicle rigging, and industrial lifting scenarios.

Forged in grade 316L stainless steel, this shackle delivers superior corrosion resistance in saltwater and chemically aggressive environments where standard steel would degrade rapidly. The material selection ensures sustained strength even after extended exposure to marine spray, humidity, and offshore conditions. Working load limits are certified for industrial applications including mechanical lifting, rigging, and tactical equipment attachment. CE marking and batch traceability confirm compliance with European safety standards and provide full documentation for equipment audits and liability chains.

This shackle is specified by operators requiring absolute reliability in rigging systems—vessel mooring, recovery equipment, load securement on tactical platforms, and industrial hoisting where the cost of failure far exceeds the investment in premium hardware. The compact 5mm diameter makes it suitable for applications requiring lightweight rigging without sacrificing load capacity or safety margins. The self-locking feature distinguishes it from standard screw-pin shackles, which can gradually back out under sustained vibration or repetitive shock loads.
