def black_bolt_shear(dia, n, fu):
    '''

    Args:
        dia (int) diameter of bolt
        n (str) number of shear plane(s) through which bolt is passing
        fu (float) ultimate tensile strength of a bolt

    Returns:
        Shear capacity of bearing type bolt in kN

    '''
    A = net_area_calc(dia)
    root3 = math.sqrt(3)
    Vs = fu * n * A / (root3 * 1.25 * 1000)
    Vs = round(Vs.real, 3)
    return Vs
