A Flange Bolt as per DIN 6921 is a high-performance fastener featuring an integrated washer-like flange beneath the hexagonal head. This flange distributes clamping force over a wider area, reducing surface damage and eliminating the need for a separate washer.

Designed for high-vibration and load-bearing applications, DIN 6921 flange bolts provide excellent resistance to loosening and ensure strong, secure fastening. The serrated or plain flange (as per requirement) improves grip and stability, making these bolts ideal for automotive, machinery, and structural uses.

Flange bolts are widely preferred where speed of assembly, uniform load distribution, and long-term reliability are critical.
