Hex Flange Bolts - Steel, M5 To M20 Sizes, Metric Right-hand Thread | Serrated Head For Enhanced Grip, Din 6921 Compliance

We export Hex flange bolts that are used on vehicle frames, especially truck frames, and anywhere a hex washer head bolt is needed. The large bearing surface distributes clamping force over a large area, allowing them to be used with irregular and over sized holes.
Hex flange bolts are often used with flange style lock nuts to create a bolt/nut system that resists loosening and spans a wide area.
They are also known as: hex frame flange bolts, hex washer frame bolts, hex flange screws.
Serrated hex flange bolts have teeth under their head that grip the mating surface to resist loosening.
