About Flange Bolts

A flange bolt has a hexagon head with a wide circular flange. The flange spreads the clamping force over a larger area, so a separate washer is often not needed. Serrated flanges also resist loosening from vibration. The common standards are DIN 6921 and ISO 4162.

Applications

Automobile and two-wheeler assemblies
Pumps, motors and compressors
Sheet metal, ducting and enclosures
Solar and structural brackets

Flange Bolt FAQs

Do I need a washer with a flange bolt?

Usually not, because the flange acts as a built-in washer. Use a separate washer only on soft material or oversize holes. Pair flange bolts with our flange nuts for a vibration-resistant joint.
