Black Nitride

Discover the unmatched durability and performance of our Black Nitride-treated hardware including quick links, bow shackles, d-shackles, and more. Engineered through a process of thermal chemical diffusion, Black Nitride offers a hardened surface "impregnated" with enhanced properties. This hardware becomes not merely coated, but transformed from within. With a case depth of 0.001", matching even NASA's standards, it increases wear resistance, improved fatigue strength, and superior lubricity.

Black Nitride products are ideal for demanding applications, from oil and gas exploration to deep space exploration, Black Nitride hardware excels where strength, precision, and longevity matter most. This treatment also provides excellent corrosion protection thanks to the quench bath all while being a lower cost than traditional hard chrome or nickel plating. The sleek, dark finish adds not only performance benefits, but also a clean and professional look.
