Fuel metering components of a fuel injector that allow spray targeting and distribution of fuel to be configured using non-angled or straight orifice having an axis parallel to a longitudinal axis of the fuel metering components. Metering orifices are located about the longitudinal axis and defining a first virtual circle greater than a second virtual circle defined by a projection of the sealing surface onto the metering disc so that all of the metering orifices are disposed outside the second virtual or bolt circle within one quadrant of the circle. A channel is formed between the seat orifice and the metering disc that allows the fuel injector to generate an unified spray pattern along the longitudinal axis that forms a flow area with a plurality of uniform radii on a virtual plane transverse to the longitudinal axis. The fuel injector of the preferred embodiments is therefore insensitive to the angular orientation of the fuel injector or its metering components about a longitudinal axis without resorting to angled metering orifices and yet achieves a desired targeting, distribution and atomization of the fuel injector. A method of generating the flow area with a plurality of uniform radii is also provided.
