Flange bolts are a type of fastener that combines a bolt and a flange nut. The flange is a broad, flat surface at the base of the bolt head, which acts as an integrated washer. This design helps distribute the load and provides a larger gripping surface. Flange bolts are commonly used in applications where a wider bearing surface is needed, or where the joint requires additional stability.

Key features of flange bolts include:

• Integrated Washer: The flange serves as a built-in washer, eliminating the need for a separate washer. This can simplify assembly and reduce the number of components.
• Increased Surface Area: The flange provides a larger surface area for load distribution. This can be beneficial in applications where the bolted joint is subject to heavy loads or where a more stable connection is required.
• Reduced Risk of Loosening: The integrated washer helps prevent the bolt from loosening over time, providing better resistance to vibration and movement in the joint.
• Applications: Flange bolts are commonly used in various industries, including construction, automotive, and machinery, where a secure and stable connection is essential.
• Materials and Coatings: Like standard bolts, flange bolts can be made from different materials, such as steel, stainless steel, or other alloys. They may also be coated for corrosion resistance in harsh environments.
• Standardization: Flange bolts are available in standard sizes and are produced according to industry standards, making them interchangeable and widely accessible.

When using flange bolts, it’s important to follow proper torque specifications and installation procedures to ensure a reliable and secure connection.
