A hexagonal head bolt with a toothed flange is a fastener that has a hexagonal head and is used to tighten to create a strong connection. 

The serrated flange on a given bolt means that it has a special design with teeth or ribs that provide additional resistance to loosening the bolt. The notched flange adheres tightly to the base of the material, preventing it from breaking under force.

Applications: automotive industry, construction, electrical and electronics, shipbuilding and aviation.

Material of manufacture: high-strength structural alloy steel. The high strength class of 8.8 allows the bolts to be used in highly loaded connections.
