Hex Head Bolt , Metric - Steel - Grade 8.8 - ZY (Zinc Yellow Passivated)) - DIN 931 Yellow zinc is most commonly used for automotive parts because it provides a good level of corrosion resistance. Black zinc offers a little less corrosion resistance than yellow zinc. Blue or clear zinc plating provides the least amount of corrosion resistance.
