VEHICLE IDENTIFICATION NUMBER DESCRIPTION The Vehicle Identification Number (VIN) plate is attached to the top left side of the instrument panel. The VIN contains 17 characters that provide data con- cerning the vehicle. Refer to the decoding chart to determine the identification of a vehicle. To protect the consumer from theft and possible fraud the manufacturer is required to include a Check Digit at the ninth position of the Vehicle Identification Num- ber.

FASTENER IDENTIFICATION DESCRIPTION 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 10.9. 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. Bolt Markings and Torques - Metric Bolt Markings 8.8/8.9 10.9 12.9 Bolt Dia. N·m Ft. Lbs. N·m Ft. Lbs. N·m Ft.
