An electromagnetic fuel injector includes an armature stop member, providing a flat surface with the lower body portion being of semi-spherical configuration, which is pivotably positioned in a conforming ball socket provided in the free end of an armature so that the flat surface extends outboard of the armature whereby it can abut against an associate pole piece to provide for a fixed minimum air gap between the pole piece and armature. In the event of any slight skewness between the axis of the pole piece and the reciprocating axis of the armature, the armature stop member will pivot, as necessary, to effect parallelism of the flat surface thereof with the flat working surface of the pole piece.
