*These torque values are approximate and should not be accepted
as accurate limits. Indeterminant factors (surface finish, type of
plating and lubrication in specific applications preclude the
publication of accurate values for universal use. Manufacturers
of various types of equipment usually provide specific tightening
instructions which should be followed. DO NOT USE the above
values for gasketed joints or joints of soft materials. DO NOT USE
your torque wrench for values greater than its maximum scale
reading.
