This paper presents photon-like spatially finite soliton solutions of screw
type to the vacuum field equations of Extended Electrodynamics (EED) in
relativistic formulation. Also, a new description of the spin momentum
inside EED, based on the notion for energy-momentum exchange between F and
*F, is introduced and used to compute the integral spin momentum of a screw
soliton. The Planck's formula 
in the form of ET=h arises as a
measure of the integral spin momentum.
