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

The Wichard Self-Locking Large Shackle — Diameter 5mm (3/16") — is a marine-grade stainless steel rigging component engineered for applications demanding secure, vibration-resistant load attachment. Forged from grade 316L stainless steel, this self-locking shackle features a pin design that locks into one of two indentations on the clevis, eliminating the risk of accidental loosening under vibration or shock loads. This design principle is critical for offshore, tactical recovery, and industrial lifting operations where pin migration can create catastrophic failure points.

The 5mm diameter and 3/16-inch specification deliver outstanding working and breaking loads suitable for industrial and marine applications. Grade 316L stainless steel provides superior corrosion resistance in salt-air and immersion environments — a critical advantage over standard stainless (316) for sustained offshore use. Each unit carries CE marking and batch number traceability, meeting European conformity standards for load-bearing equipment. The shackle's self-locking mechanism is passive and maintenance-free, requiring no secondary locking devices, tape, or safety wire.

This shackle is designed for industrial lifting, vessel rigging, tactical recovery operations, and any scenario where unsecured pins present a liability. Operators and riggers working in offshore, maritime, or high-vibration environments value the self-locking feature because it reduces inspection intervals and eliminates a common failure vector. The compact size and robust construction make it suitable for confined spaces and demanding field conditions where reliability is non-negotiable.

Wichard Marine is known for precision marine hardware used by commercial and naval operators worldwide. The grade 316L material and European certification distinguish this shackle from commodity alternatives, making it a dependable choice for professionals who specify equipment by engineering standards rather than price alone.
