The coarse thread design allows for quicker assembly and better resistance to cross-threading, especially in environments where speed and ease of use are critical.

Each nut is manufactured from low carbon steel, offering a balance of strength and ductility that makes them easy to install and remove without compromising structural integrity. The zinc plating with CR+3 trivalent chromium provides enhanced corrosion resistance compared to traditional zinc finishes, making these nuts suitable for both indoor and light outdoor use. This finish also gives the nuts a clean, bright appearance that resists tarnishing over time.
