Flange Nut - Overview

A flange nut is a type of nut that has a wide rim or flange at one end, acting as a built-in washer. This flange helps distribute the clamping force over a larger area, reducing the risk of damage to the material being fastened and providing a more secure connection, especially on uneven surfaces.

Types of Flange Nuts

Serrated Flange Nuts

These flange nuts have serrations (small ridges or teeth) on the underside of the flange. The serrations grip the surface of the material, providing increased resistance to loosening due to vibrations. Serrated flange nuts are often used in automotive and machinery applications. See specifications below.

Non-Serrated Flange Nuts

Unlike serrated flange nuts, non-serrated flange nuts have a smooth underside. They are commonly used in applications where marring or damaging the surface of the material is a concern. See specifications below.

Advantages of Flange Nut

Integrated Flange Provides Better Load Distribution

A flange nut has a built-in wide base (the flange) that helps spread the load across a larger surface area. This reduces the risk of damage to the connected parts and increases the nut's holding strength, especially on softer materials.

Enhanced Grip and Vibration Resistance

The serrated edge on the flange nut grips better onto surfaces, reducing the likelihood of loosening due to vibrations. This makes them ideal for use in machinery or automotive applications where vibrations are common.

No Need for a Washer

Unlike normal nuts, flange nuts don't typically require a washer (spring washer or tooth washers). The flange itself acts as a washer, saving both time and material during assembly. This also simplifies the assembly process and reducing installation errors.

Application

Construction and Manufacturing

Flange nuts are frequently used in structural applications in the construction and manufacturing industries. They are commonly used to secure beams, panels, and other structural components, providing a reliable connection that can withstand various stresses. The load distribution properties of flange nuts make them suitable for both temporary and permanent installations.

Automotive and Aerospace

Flange nuts are widely used in the automotive and aerospace industries due to their strength and reliability. In automotive assembly, they are used to secure components such as engines, transmissions, and suspension systems. In aerospace applications, where safety and performance are paramount, flange nuts provide the necessary security and stability for critical components.

Electrical and Electronic Applications

Flange nuts can also be used in electrical and electronic applications. They can secure connectors, circuit boards, and other components to ensure a stable and reliable connection. The flange design helps prevent damage to the circuit board, making it a preferred choice for electronic components.

Bolts Used with Flange Nuts

Hex Head Bolts

Hexagonal head bolts, often referred to as hex bolts, are a common choice when paired with flange nuts. They provide a sturdy and reliable connection and are widely used in construction, machinery, and structural applications.

Socket Cap Screws

Socket cap screws are another option when using flange nuts. They have a recessed hexagonal socket in their head, allowing for secure tightening with an Allen wrench or hex key. Socket cap screws are often used in precision equipment and machinery.

Carriage Bolts

Carriage bolts have a round head with a square shoulder just beneath it. Flange nuts are used with carriage bolts when a smooth and finished appearance is desired. These are commonly found in outdoor furniture and wooden structures.

Stud Bolts

In applications where flange connections are prevalent, stud bolts and flange nuts are used together to create a reliable and leak-proof joint. This combination is commonly employed in the oil and gas industry for connecting pipelines and flanges.
