Advantages of the product

Integrated Flange Design for Secure, Vibration-Resistant Fastening

Our flange nuts feature a wide, integrated flange at the base that replaces the need for a separate washer. This flange distributes the clamping force over a larger area, reducing surface pressure and preventing damage to the connected material. The serrated (or non-serrated) underside of the flange bites into the bearing surface, providing excellent resistance to loosening caused by vibration, which is common in automotive, machinery, and equipment assembly. This design ensures a more secure and reliable connection.

Corrosion-Resistant Coatings for Enhanced Flange Nut Longevity

To protect against corrosion, our flange nuts are available with various surface treatments. These include electroplated zinc, geometric diffusion coating, and hot-dip galvanizing. For severe environments, we offer nuts made from stainless steel (A2-70 or A4-80). These coatings and materials ensure the nut maintains its structural integrity and appearance over time, even when exposed to moisture, chemicals, or outdoor weather conditions, thereby extending the service life of the assembly.

Wide Range of Sizes and Thread Specifications for Flange Nuts

We stock a comprehensive range of flange nuts in standard metric and imperial sizes, with fine and coarse thread pitches. This extensive selection ensures compatibility with a wide variety of bolts and screws. The availability of different flange styles, such as smooth or serrated, allows for selection based on the specific requirement for vibration resistance or surface protection. This variety makes it easy for customers to find the exact flange nut needed for their project.

Common problem

Are the flanges on your nuts serrated or plain?

We offer both serrated and plain flange nuts. Serrated flanges have teeth that bite into the bearing surface, providing a self-locking effect that resists vibration-induced loosening. Plain flanges are suitable for applications where surface damage must be avoided. We help customers choose the right type based on their need for vibration resistance and surface preservation.
Absolutely. We manufacture flange nuts in various strength grades to match high-strength bolts. These nuts are made from alloy steels and undergo controlled heat treatment to achieve the required mechanical properties, ensuring they can handle the high preloads necessary for critical structural connections without stripping or failing.
Yes, we offer flange nuts in carbon steel, stainless steel (SS304, SS316), and other materials. This allows customers to select nuts for corrosion resistance, weight, or material compatibility. Our comprehensive range ensures we can meet the specific environmental and mechanical demands of your project.
