  Motivated by the growing attention devoted to the Quantum Chromodynamics
sector of the Standard Model, and the recent observations of non-standard
hadronic states, a possible substructure of quarks $q_{f}\equiv
C_{ij}|k_{i}k_{j}\rangle $ in terms of four colorless bound particles $%
k_{i(=0,\ldots,3)}$ "hyperquarks" is investigated in a $SO(10)$-inspired
unified model. This aims to define a subtle structure of matter as well as an
explanation of some particularities of quarks. Precisley, these hyperquarks
$k_{i}$ are bound by a $SU(3)_{h}$ "hyperstrong force" under which they are
assumed to be charged. Exploiting certain known data, the masses and the
charges of such fundamental particles are discussed along with the emerged four
extra quarks $q_{f}\equiv \delta_{ii}|k_{i}k_{i}\rangle $ and three hyperweak
bosons $W_{h}$.
