This spanner wrench is an authentic OEM replacement part sourced directly from the manufacturer. It is used to remove the agitator nut on washing machines. The agitator nut's size and shape make it difficult to access and remove with standard household tools. The spanner wrench is designed with greater torque just for this purpose. If the washing machine's agitator is not working properly or if parts behind it need to be repaired, this wrench makes it easier to remove the nut and then take the agitator out.To use the spanner wrench, slide the center hole over the nut and turn. The hole's location makes turning the spanner wrench simple because it has handles on both sides of the hole and slides over the nut, not around it like many wrenches. Once the agitator has been removed and put back in place, the spanner wrench should be labeled and stored where it is easily accessible for future use.This spanner wrench is made of high-strength black metal and is sold individually. It is designed for use on the agitator nut of washing machines manufactured by General Electric and Hotpoint.
