Durable Hex Flange Bolt

We are engaged in exporting excellent quality Durable Hex Flange Bolt to our valuable clients. Hex flange bolts 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 oversized 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.
