This talk summarizes results for all the scale independent renormalization constants for bilinear currents ( Z A, ZV, and Zs/Zp), the improvement constants (CA, CV, and CT), the quark mass dependence of 20, and the coefficients of the equation of motion operators for O(a) improved lattice QCD. Using data at p = 6.0, 6.2 and 6.4 we study the scaling behavior of these quantities and quantify residual discretization errors.
