8.8 Zinc Plated Steel Hexagon Flange Bolts Metric

Hex head flange bolts are a hexagonal head bolt with an integral washer attached as a flange. Like a washer, the flange spreads the load of the bolt head onto the adjoining surface. The underside of the flange can be serrated or plain. The serrations help to grip the bolt head to the surface, whereas the plain underside will protect the surface.
