Its primary design advantages and functions are:
- Integrated Load Distribution: The key feature is the flange, which provides a widened bearing surface. This distributes the clamping force over a larger area than a standard bolt head alone, reducing surface pressure and helping to prevent damage to the assembled material.
- Vibration Resistance and Stability: The flange often has a serrated or toothed underside (on serrated flange bolts). These teeth bite into the mating surface upon tightening, providing a strong locking action against vibration and rotation, often eliminating the need for a separate lock washer.
- Efficiency in Assembly: By combining the bolt and washer into a single component, it simplifies parts inventory and speeds up assembly, as there is one fewer piece to handle.
Flange bolts are widely used in applications where reliable, vibration-resistant joints are needed on softer or painted surfaces. Common applications include automotive bodywork, sheet metal fabrication, plastic components, electrical enclosures, and general machinery. They are typically standardized under specifications such as DIN 6921 (for metric sizes).
