Carbon steel non-standard inner hexagon flange bolts

Comparable in strength to Grade 9 steel screws, these screws are about 20% stronger than high-strength steel flanged screws. Use them for heavy duty stamping applications as well as earth-moving machinery, such as bulldozers and excavators. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. The black-oxide finish provides mild corrosion resistance in dry environments. Head height includes the flange. Length is measured from under the flange.
