Threaded Rod Connectors

Threaded Rod Connectors, also commonly known as Coupling Nuts, are elongated hexagonal nuts designed to join two threaded rods or studs together to extend their length. Zeron Fasteners manufactures high-quality connectors in a variety of materials, including Stainless Steel (304, 316), Carbon Steel, and Alloy Steel. These fasteners are essential for suspended ceiling installations, electrical tray support, and HVAC ducting where continuous rod lengths are required. Our connectors are precision-machined to ensure smooth thread engagement and maximum load-bearing capacity, often featuring a sight hole in the center to verify that the rods have been fully and equally engaged from both ends.
