Dirac plus Nambu monopoles in the Standard Model

We show how in the standard electroweak model three $SU(2)_L$ Nambu monopoles, each carrying electromagnetic (EM) and Z- magnetic fluxes, can merge (through Z-strings) with a single $U(1)_Y$ Dirac monopole to yield composite that only carries EM flux. Compatibility quantization condition requires this carry six quanta ($12 \pi /e$) of charge, independent mixing angle $\theta_w$. The is not regular at origin energy therefore divergent. discuss problem cured by embedding grand unified group such as $SU(5)$. A second configuration one colored has minimal charge $4\pi/e$ also described. Finally, there exists an $8\pi/e$ well screened color charge.
