SPECIFICATION NOTATIONS
WARNING: THE USE OF INCORRECT ATTACHING
HARDWARE CAN RESULT IN COMPONENT DAM-
AGE AND/OR PERSONAL INJURY.
It is important to retain the original attaching
hardware for assembly of the components. If the at-
taching hardware is not reusable, hardware with
equivalent specifications must be used.
METRIC AND ENGLISH/SAE CONVERSION
The following chart will assist in converting metric
units to equivalent English and SAE units, or vise
versa.
TORQUE SPECIFICATIONS
TORQUE CHARTS
A torque chart for fasteners is provided at the end
of each group (of service information). Refer to the
Torque Specifications chart to determine torque val-
ues not listed in the group.It is important to be aware that the torque values
listed in the chart are based on clean and dry bolt
threads. Reduce the torque value by 10 percent when
the bolt threads are lubricated and by 20 percent if
new.
BOLT THREAD AND GRADE/CLASS
IDENTIFICATION
THREAD IDENTIFICATION
SAE and metric bolt/nut threads are not the same.
The difference is described in the Thread Notation
chart.
GRADE/CLASS IDENTIFICATION
The SAE bolt strength grades range from grade 2 to
grade 8. The higher the grade number, the greater
the bolt strength. Identification is determined by the
line marks on the top of each bolt head. The actual
bolt strength grade corresponds to the number of line
marks plus 2. The most commonly used metric bolt
strength classes are 9.8 and 12.9. The metric strength
class identification number is imprinted on the head
of the bolt. The higher the class number,

the greater the bolt strength. Some metric nuts areimprinted with a single-digit strength class on the
nut face. Refer to the bolt identification and bolt
strength chart.
METRIC CONVERSION
Refer to the chart to convert torque values listed in
metric Newton-meters (Nzm). Also, use the chart to
convert between millimeters (mm) and inches (in.)
