Effective temperatures, bolometric corrections, radii and luminosities are determined for seven F stars, based on low-dispersion spectra obtained from the IUE satellite, the spectrophotometric catalog of the Sternberg State Astronomical Institute and infrafred photometry data. Comparison with the theoretical models of Kurucz shows that for four stars the observed energy distribution is lower than the theoretical one in the 3200-3700 A range. For three stars there is good agreement with the models. Two stars, however, have ultraviolet excesses in the U-B color indices and BS 7061 is atypical, since its effective temperature is 300 K lower than for stars of this spectral type.
