If 'T' is the greek 'Tau' then it is the symbol for shear stress, shear stress = Shear Force / Cross-section area, so for your example it is 2400 / 4 = 600 psi (pounds per square inch) which is a reallly really low stress... aluminum for example can sustain stresses of at least 20000psi and steel is 3x stronger.

Actually, because of the nature of shear stress distribution, for a round bolt, Tmax = (4/3)V/A = 800 psi.
Various other shapes have their own coefficients.....Source(s): MSME

As a side note, if you can help it, design your bolts so they are in tension or compression. If you have a shear load, it should be carried by a key or something of that nature.
