Flange Bolts

DESCRIPTION:

A flange bolt is a type of threaded fastener designed with an integrated flange, or washer-like, disc under the head. This flange serves several purposes and provides advantages in certain applications:

1. Distribution of Load: The flange on a flange bolt acts as a built-in washer, distributing the load or pressure more evenly across the surface of the material being fastened. This can help prevent damage to softer materials and reduce the risk of over-tightening.
2. Vibration Resistance: Flange bolts are commonly used in applications where vibration is a concern. The flange helps to prevent the bolt from loosening due to vibration because it provides a larger contact surface area, which increases friction and prevents rotation.
3. Reduced Galling: Galling is a common problem with threaded fasteners made of stainless steel or other materials. It occurs when the threads seize or lock together during tightening. The flange on a flange bolt can reduce the risk of galling because it creates a separation between the bolt head and the material’s surface.
4. Easy Assembly: Flange bolts can be easier to install because they do not require a separate washer. This can save time during assembly and reduce the number of components needed.
5. Weather Resistance: The flange on a flange bolt can also act as a sealing surface, helping to prevent moisture and contaminants from entering the joint. This makes them suitable for outdoor and weather-exposed applications.

Flange bolts come in various styles and materials to suit different applications. They have hexagonal heads, and they are available in a range of materials, including carbon steel, stainless steel, and other alloys. The choice of flange bolt depends on the specific requirements of the application, including load-bearing capacity, corrosion resistance, and environmental conditions.

Overall, flange bolts are a versatile fastening solution used in a wide range of industries and applications where their unique design provides advantages in terms of load distribution, vibration resistance, and ease of assembly.
