Nearby detached double-lined eclipsing binaries with most accurate data were studied and 290 systems were found with at least one main-sequence component having a metallicity of 0.008 <= Z <= 0.040. Stellar parameters, light ratios, Gaia Data Release 2 trigonometric parallaxes, extinctions and/or reddening were investigated and only 206 systems were selected as eligible to calculate empirical bolometric corrections. NASA/IPAC Galactic dust maps were the main source of extinctions. Unreliable extinctions at low Galactic latitudes |b| <= 5° were replaced with individual determinations, if they exist in the literature, else associated systems were discarded. The main-sequence stars of te remaining systems were used to calculate the bolometric corrections (BCs) and to calibrate the BC-T_eff relation, which is valid in the range 3100-36 000 K. De-reddened (B - V)₀ colours, on the other hand, allowed us to calibrate two intrinsic colour-effective temperature relations; the linear one is valid for T_ eff_> 10 000 K, while the quadratic relation is valid for T_ eff_< 10 000 K; that is, both are valid in the same temperature range in which the BC-T_eff relation is valid. New BCs computed from T_eff and other astrophysical parameters are tabulated, as well.
