A Flange Bolt is a specialized fastener with an integrated washer-like flange beneath the hexagonal head, providing a wider bearing surface for better load distribution and preventing damage to the assembled parts. The flange eliminates the need for a separate washer, ensuring faster and more efficient assembly. ... Flange bolts are available in fully or partially threaded designs and are typically made from materials like carbon steel, stainless steel, or alloy steel for durability and corrosion resistance. Widely used in automotive, machinery, and structural applications, they are ideal for securing components with high torque and vibration, ensuring reliability in demanding environments.
