Flange Bolts

Understanding Flange Bolts

Flange bolts are a specialized type of fastener with a flange at one end, which acts as an integrated washer. This design distributes the pressure of the nut over a wider area, which in turn provides a more secure hold. Ideal for applications where a flat bearing surface is necessary, the flange bolts are a staple in various industries, from automotive to heavy machinery.

Types and Applications of Flange Bolts

There are several types of flange bolts, such as the hex flange bolt and the 12 point bolts, each serving a specific purpose. The hexagon flange bolt, known for its six-sided head, is commonly used in automotive and construction applications. On the other hand, 12 point bolts offer a higher degree of torque precision, making them suitable for aerospace and engine applications where space is limited and exactitude is crucial.

Materials and Features

Flange bolts are typically made from carbon steel, stainless steel, or alloy steel, with finishes that may include zinc plating or black oxide for corrosion resistance. The flange head screws are designed to eliminate the need for a separate washer, streamlining the assembly process and reducing the risk of component failure due to uneven load distribution.

Advantages of Using Flange Bolts

The use of flange bolts, such as closet flange bolts in plumbing or ucf208 and ucf205 in mounting applications, offers several advantages. Their unique design ensures a tight seal, which is particularly beneficial in applications involving piping, like the ucfl206 and ucf210, where preventing leaks is crucial. Moreover, the flange provides additional surface area, which helps in distributing the load evenly, thereby enhancing the structural integrity of the assembly.

Installation and Compliance

When selecting flange bolts for any project, it is essential to consider the standards they must meet. Bolts conforming to din 6921 specifications, for instance, are recognized for their quality and consistency. Compliance with standards such as asme pcc 1 ensures that the bolts are suitable for their intended use, especially in critical service conditions where failure could result in significant consequences.

Choosing the Right Flange Bolts

Selecting the correct flange bolt, like the ucfl205 or ucfl204, requires understanding the specific needs of the application. Factors such as the environment, load requirements, and the materials being fastened will influence the choice of bolt. For specialized applications, such as securing a toilet base, toilet anchor bolts are designed to provide a firm hold and easy installation.
