What is Hex Coupler Nut?

Coupler nut (also known as a rod coupling, rod coupling nut, coupling nut, or extension nut), is a threaded fastener for joining two male threads, most commonly threaded rods. The outside surface of the coupling nut is usually a hex shape to allow for wrench tightening. Reducing coupling nuts are a variant design that allows the joining of two rods of differing thread sizes.

Product adavantages

▲Precision Machining
Measure and process using precision machine tools and measuring tools under strictly controlled environmental conditions.

▲High-quality carbon steel
With long life, low heat generation, high hardness, high rigidity, low noise, high wear resistance and other characteristics.

▲Cost-effective
The use of high-quality carbon steel steel, after precision processing and forming, greatly improves the user experience.

Applications

Coupler nuts, also known as extension nuts, are elongated internally threaded nuts used to join two male threads. Coupling nuts are often used for joining threaded rods or hanger bolts in a variety of applications that require extending threaded rod or attaching like items.

surface treatment

▲BLACK
Black is a common method for metal heat treatment. The principle is to make an oxide film on the metal surface to isolate the air and achieve rust prevention.

▲ZINC
Electro-galvanizing is a traditional metal coating treatment technology that provides basic corrosion resistance to metal surfaces. The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating.

▲HDG
The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating. Hot-dip zinc has good corrosion resistance, sacrificial protection for steel substrates, high weather resistance, and resistance to salt water erosion. It is suitable for chemical plants, refineries and coastal and offshore operating platforms.
