Serrated-Flange Socket Head Screws Serrations under the head grip the material's surface for mild vibration resistance, and the flange distributes pressure, eliminating the need for a separate washer. With a tensile strength of 140,000 psi, these alloy steel screws are comparable in strength to Grade 8 steel screws and are stronger than stainless steel screws. Their black-oxide finish provides mild corrosion resistance in dry environments. Head height includes the flange. Length is measured from under the flange.
