Flange Bolts
Flange bolts are hex-head bolts with an integrated washer-like flange under the head. This built-in bearing surface spreads clamping load, helps protect mating materials, and often eliminates the need for a separate washer, speeding up assembly and reducing parts count. Many flange bolts feature serrations on the underside of the flange to resist loosening in high-vibration environments.
American Bolt Corp stocks flange bolts in hex flange, serrated flange, and metric styles for reliable fastening across automotive OEM, industrial, and manufacturing applications. Choose from multiple sizes, strengths, and finishes to match your load requirements and corrosion environment.
