Wichard 1303W Self-Locking Allen Head Pin D Shackle 6mm 1/4" Grade 316L Stainless Steel

The Wichard 1303W is a self-locking Allen head pin D shackle forged from grade 316L stainless steel, delivering exceptional strength, corrosion resistance, and reliability for marine and industrial applications. With a 6mm (1/4") pin diameter, this shackle is engineered for secure, snag-free connections wherever dependable hardware is required.

The pin locks into one of the indentations on the shackle body, and its flush head design means it sits completely recessed — eliminating any risk of snagging on lines, sails, or rigging. The positive locking mechanism also prevents the pin from backing out due to vibration, making this shackle ideal for high-motion marine environments.
