    Tightening torque: 

    Calculation formula

    T = 15 N.m (1.5 kgf-m, 11.1 ft-lb) x L1/(L1 + L2)

    T: Reading of the torque wrench

    L1: Effective length of the torque wrench

    L2: Effective length of the crowfoot wrench

    NOTE:

    If the effective length of the tool used is unknown, consult the manufacturer of the tool.
