FASTENER IDENTIFICATION
THREAD IDENTIFICATION
SAE and metric bolt/nut threads are not the same. The difference is described in the Thread Notation chart (Fig. 3).
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 are imprinted with a single-digit strength class on the nut face. Refer to the Fastener Identification and Fastener Strength Charts.

FASTENER USAGE
WARNING: USE OF AN INCORRECT FASTENER MAY RESULT IN COMPONENT DAMAGE OR PER- SONAL INJURY.
Figure art, specifications and torque references in this Service Manual are identified in metric and SAE format.
During any maintenance or repair procedures, it is important to salvage all fasteners (nuts, bolts, etc.) for reassembly. If the fastener is not salvageable, a fastener of equivalent specification must be used.
THREADED HOLE REPAIR
Most stripped threaded holes can be repaired using a Helicoilt. Follow the manufactures recommendations for application and repair procedures.
METRIC SYSTEM
WARNING: USE OF AN INCORRECT FASTENER MAY RESULT IN COMPONENT DAMAGE OR PER- SONAL INJURY.
Figure art, specifications and torque references in this Service Manual are identified in metric and SAE format.
CONVERSION FORMULAS AND EQUIVALENT VALUES
During any maintenance or repair procedures, it is important to salvage metric fasteners (nuts, bolts, etc.) for reassembly. If the fastener is not salvageable, a fastener of equivalent specification should be used.
The metric system is based on quantities of one, ten, one hundred, one thousand and one million (Fig. 4).
The following chart will assist in converting metric units to equivalent English and SAE units, or vise versa.
Refer to the Metric Conversion chart to convert torque values listed in metric Newton- meters (N·m). Also, use the chart to convert between millimeters (mm) and inches (in.)
TORQUE REFERENCES
Individual Torque Charts appear at the end of many Groups. Refer to the Standard Torque Specifi-
