1. 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 Grade G 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.


A flange screw with a serrated hex washer is an un-slotted hex head screw style with a unified thread pitch, and a flange that has serrations on the bearing surface side. These screws are designed for use in applications where vibrations can loosen fasteners. The serrations grip the bearing surface so that significantly more torque is needed to loosen the screw than it does to tighten it. The flange provides more strength than a standard machine screw and eliminates the need for a lockwasher or locknut in certain applications.
