A Flange Nut is a nut with an integrated, wide flange that acts like a built-in washer. The flange distributes the tightening load over a larger surface area, helping reduce pressure on the secured component and improving fastening stability. It can also help cover oversized holes and compensate for uneven fastening surfaces.
Flange nuts are available in both non-serrated and serrated designs. Serrated flange nuts provide additional locking action by creating resistance against rotation when tightened, making them suitable for applications where vibration or movement may cause a conventional nut to loosen.
Key Features
- Integrated flange eliminates the need for a separate washer in many applications.
- Wide flange distributes the fastening load over a larger surface area.
- Helps reduce the risk of damage to the secured component.
- Available in serrated and non-serrated designs.
- Serrated versions provide additional resistance against loosening.
- Suitable for applications exposed to vibration and mechanical movement.
- Available in stainless steel, carbon steel, and alloy steel.
- Offered with different finishes and coatings according to application requirements.
Applications
Flange nuts are commonly used in:
- Industrial machinery and equipment
- Automotive and mechanical assemblies
- Electrical and machining components
- Manufacturing and fabrication
- Construction and engineering applications
- Equipment exposed to vibration or movement
- Large-scale projects requiring efficient fastening
- General maintenance and repair applications
Serrated and Non-Serrated Flange Nuts
Non-serrated flange nuts provide a smooth bearing surface and are suitable where the mating surface should remain protected from scratching.
Serrated flange nuts feature angled serrations beneath the flange. When tightened, these serrations create additional resistance against rotation and help maintain the holding force of the connection. Because the serrations can mark or scratch the mating surface, they are generally used without washers on suitable surfaces.
Materials and Construction
Flange nuts are commonly manufactured from carbon steel, stainless steel, and alloy steel to meet different strength, durability, and corrosion-resistance requirements. Hardened steel options and protective coatings can also be supplied depending on the application.
