FEATURES

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. Serrated hex flange bolts have teeth under their head that grip the mating surface to resist loosening. 12 point flange bolts, also called counterbore cap screws, are used in aircraft and aftermarket automotive applications because they are easily installed using a 12 point socket and pneumatic impact wrench, while motorcycle enthusiasts like the small, externally wrenched decorative head.
