Flange Nut
Fastening connection products with a flange face.

Product Introduction
A flange nut is a hex nut with an integrated flange base that can replace a washer, increasing the bearing area and making the connection more stable. Additionally, the flange structure reduces pressure damage on the surface of the connected parts, improving fastening reliability.
WT Fasteners specializes in producing various specifications of flange nuts, including plain flange nuts and serrated flange nuts (locking flange nuts). We can provide different materials, strength grades, and surface treatment options according to customer requirements. These are widely used in automotive, machinery, construction, power equipment, and industrial assembly fields.
Product Features
1. Integrated Flange Design
The bottom flange increases the contact area between the nut and the workpiece, dispersing fastening pressure and improving connection stability.
2. Excellent Anti-Loosening Performance
Serrated flange nuts bite into the mating surface with teeth, effectively enhancing vibration resistance, suitable for vibrating environments.
3. Quick and Easy Installation
No additional flat washers are needed, reducing the number of parts and improving assembly efficiency.
4. High-Strength Manufacturing
Made from high-quality carbon steel, alloy steel, and stainless steel, offering excellent mechanical properties and durability.
5. Customization Supported
Special specifications, threads, materials, and surface treatments can be customized based on customer drawings or samples.
