Grade 10.9 M16 Alloy Steel Flanged Hex Head Bolts
Good for demanding applications such as suspension systems, these screws are at least 25% stronger than medium-strength steel screws. They have a flange that distributes pressure where the screw meets the surface, eliminating the need for a separate washer. The black-phosphate finish provides corrosion resistance in wet environments. Head height includes the flange. Length is measured from under the flange.
