Product Description

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.
