Serrated Flange Bolts W151 FL

Serrated Flange Bolts are a hexagon head bolt with a washer like flange built onto the head that has serrations on the bottom of the flange.

The teeth of the serrated flange will penetrate into the mating surface when tightened which will help to prevent the fastener from backing itself out. When the fastener is removed the teeth will shear off the material that they have penetrated into.
