Wichard 1344W Self-Locking Allen Head Pin Bow Shackle 8mm 5/16"

The Wichard 1344W is a self-locking Allen head pin bow shackle drop-forged in grade 316L stainless steel, purpose-built for demanding marine and industrial environments. The wide, rounded bow design accommodates multiple lines or cables simultaneously, making it ideal for rigging, anchoring, and deck hardware applications where ample attachment room is needed.

The defining feature of this shackle is its self-locking pin mechanism: as the pin is tightened, small lugs on the pin engage precisely machined indentations in the shackle body, preventing the pin from rotating loose due to vibration. The Allen (hex) head pin allows for secure tightening and removal with a standard hex key, providing a cleaner, snag-free profile compared to a standard eye-bolt pin.

Key Features:

• Drop-forged grade 316L stainless steel construction for superior strength and corrosion resistance
• Self-locking Allen head pin — pin locks into shackle body indentations to prevent accidental release from vibration
• Bow (anchor) shackle design allows attachment of several lines or cables simultaneously
• Working Load (nautical): 2,200 lb | WLL (industrial): 1,190 lb | Breaking Load: 5,950 lb
• CE marked and batch numbered for traceability
• Designed and manufactured in France
• High-polish finish for aesthetics and corrosion resistance
• WLL stamped directly on the shackle body
