Coupling Nuts are extended, internally threaded nuts designed to join two pieces of threaded rod or other male-threaded fasteners, making them essential in many industrial, structural, and scale-based assemblies. With a heavy hex exterior, these nuts offer superior torque resistance and ease of installation using standard tools.
Perfect for load cell installations, platform reinforcements, and bracket mounting, these coupling nuts offer reliable strength and alignment where standard hex nuts fall short. Their extended length adds thread engagement, reducing the risk of loosening under vibration or load shifts.
Constructed for high-load industrial use, SellEton’s coupling nuts come in a range of UNC thread sizes and safe load capacities, providing dependable performance for any scale or mechanical setup.
