A gross was a counting unit equal to a dozen dozen or 144.
In 2369, Jake Sisko and Nog traded five thousand wrappages of Cardassian yamok sauce for one hundred gross self-sealing stem bolts, in an exchange with a Lissepian freighter captain. The 14,400 stem bolts were, in turn, traded for seven tessipates of land on Bajor. (DS9: "Progress")
In 2371, Quark had his own supply of one hundred gross of self-sealing stem bolts occupying space in Cargo Bay 11. He offered them to a wealthy prospective buyer named Emi for ten bars of gold-pressed latinum. Emi was, however, later told by Grand Nagus Zek where she could get the same quantity of bolts at wholesale, for a much-reduced price. (DS9: "Prophet Motive")
