Wichard Self-Locking Bow Shackle - Diameter 4mm - 5/32"

The Wichard Self-Locking Bow Shackle in 4mm diameter (5/32") is a precision-engineered rigging component designed for tactical, maritime, and field operations where load security is non-negotiable. Built from grade 316L stainless steel, this self-locking shackle eliminates the risk of accidental pin release caused by vibration, shock, or repetitive movement—a critical failure point in standard shackles used by military personnel, law enforcement teams, and professional riggers. Whether securing gear loads, establishing anchor points, or maintaining equipment integrity during dynamic operations, this shackle delivers reliability in harsh environments.

The self-locking mechanism works through a precision-forged design where the pin sits locked into one of multiple indentations machined into the bow, preventing lateral movement and accidental loosening under stress. Grade 316L stainless steel provides superior corrosion resistance compared to standard stainless grades, making it ideal for saltwater environments, chemical exposure, and extended storage without maintenance. The compact 4mm diameter weighs only 0.05 lbs while maintaining exceptional strength-to-weight ratio, and the 5/32" designation ensures compatibility with standard NATO and tactical rigging systems, carabiners, and load-bearing equipment.

Tactical professionals, riggers, search and rescue teams, and military units benefit most from this shackle's vibration-proof design, particularly in vehicles, aircraft, or field operations where constant movement could compromise standard hardware. Installation is straightforward: insert the pin through your anchor point and the shackle bow, then seat it firmly into the locking indentation until it sits flush. The compact 2 x 1 x 6 inch form factor allows integration into gear loops, rucksack attachment points, and tight anchor configurations without bulk. This shackle for sale is an investment in equipment reliability when lives and operations depend on gear staying exactly where you secured it.
