Class 8.8 Steel White Zinc Plated Flange Hex Head Screws Zinc Plated Flange Hex Bolts
Products Descriptions
These screws are suitable for fastening most machinery and equipment. 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.
