We present a new and homogeneous set of explosive yields for masses 13, 15, 20, 25, 30, and 35 M. and metallicities Z = 0, 10(-6), 10(-4), 10(-3), 6 x 10(-3), and 2 x 10(-2). A wide network extending up to Mo has been used in all computations. We show that at low metallicities (Z less than or equal to 10(-4)), the final yields do not depend significantly on the initial chemical composition of the models, so a scaled solar distribution may be safely assumed at all metallicities. Moreover, no elements above Zn are produced by any mass in the grid up to a metallicity similar to10(-3). These yields are available for any choice of the mass cut on request.
