The SecureFix Direct 5MM Countersunk D Shackle (SFSSDC05) is an ideal hardware solution for marine enthusiasts, boat owners, and rigging professionals who require a low-profile, secure connection point. Its primary benefit is the flush-fitting pin design, which eliminates snagging and provides a clean aesthetic, though it does require a flatnose screwdriver for installation or removal rather than tool-free operation. Crafted from 316-grade stainless steel, this shackle provides the durability and rust resistance necessary for harsh, saltwater-exposed environments.

Yes, it is manufactured from 316-grade stainless steel, which is specifically chosen for its high resistance to marine corrosion.
No, it requires a standard flatnose screwdriver to operate the countersunk pin.
It has a tested breaking load of 928kg.
The countersunk design ensures the pin sits flush with the shackle body, creating a smooth finish that prevents snagging on rigging or lines.
Always check local rigging regulations, but this shackle is primarily designed for marine and general rigging use rather than overhead lifting.
Check the thread for grit or debris; clean with fresh water and ensure the screwdriver bit is a proper fit for the slot.
Verify that the pin is fully threaded into the body; do not overtighten, as it may strip the slot or damage the threads.
To install, align the pin with the shackle body and use a correctly sized flatnose screwdriver to rotate the pin until it is flush with the outer surface. Ensure the threads are clear of debris before tightening. Since this component is made from 316 stainless steel, it is naturally resistant to oxidation. However, for maximum longevity in high-salt environments, it is recommended to occasionally rinse the shackle with fresh water to remove salt deposits. Avoid using steel wire brushes for cleaning, as these can leave iron particles on the surface that may cause surface rust.
