The Harken 8mm High Resistance “D” Shackle is forged from 17-4PH stainless steel specifically to handle high loads, well beyond what a standard shackle of the same size is rated for.
It’s polished to a high luster and stamped with the screw pin diameter for quick identification, and an “HR” imprint marks it clearly as a High-Resistance model rather than a standard-duty shackle.
Rated to a 5,130-lb maximum working load with a 10,260-lb breaking load, it’s built for the kind of high-load connection point where a standard shackle would be the weak link in the system. Explore more sailing hardware.
