Metric Fasteners
This vehicle provides fastener dimensions using the metric system. Most metric fasteners are approximate in diameter to equivalent English fasteners. Make replacements using fasteners of the same nominal diameter, thread pitch, and strength.
A number marking identifies the OE metric fasteners except cross-recess head screws. The number also indicates the strength of the fastener material. A Posidrive® or Type 1A cross-recess identifies a metric cross-recess screw. For best results, use a Type 1A cross-recess screwdriver, or equivalent, in Posidrive® recess head screws.
GM Engineering Standards and North American Industries have adopted a portion of the ISO-defined standard metric fastener sizes. The purpose was to reduce the number of fastener sizes used while retaining the best thread qualities in each thread size. For example, the metric M6.0 X 1 screw, with nearly the same diameter and 25.4 threads per inch replaced the English 1/4-20 and 1/4-28 screws. The thread pitch is midway between the English coarse and fine thread pitches.

| 3 | English Bolt, Grade 7 (Strength Class) |
| 4 | English Bolt, Grade 8 (Strength Class) |
| 5 | Metric Nut, Strength Class 9 |
| 6 | Metric Bolts, Strength Class Increases as Numbers Increase |
The most commonly used metric fastener strength property classes are 9.8 and 10.9. The class identification is embossed on the head of each bolt. The English, inch strength classes range from grade 2 to grade 8. Radial lines are embossed on the head of each bolt in order to identify the strength class. The number of lines on the head of the bolt is 2 lines less than the actual grade. For example, a grade 8 bolt will have 6 radial lines on the bolt head. Some metric nuts are marked with a single digit strength identification number on the nut face.
The correct fasteners are available through GM SPO. Many metric fasteners available in the aftermarket parts channels are designed to metric standards of countries other than the United States, and may exhibit the following
- Lower strength
- No numbered head marking system
- Wrong thread pitch
The metric fasteners on GM products are designed to new, international standards. The following are the common sizes and pitches, except for special applications
- M6.0 X 1
- M8 X 1.25
- M10 X 1.5
- M12 X 1.75
- M14 X 2.00
- M16 X 2.00
Adhesive Coated Fasteners
These fasteners accomplish the thread interface by the presence of a thread-locking compound on the fastener threads. Refer to the appropriate repair procedure in order to determine if the fastener may be reused and the applicable thread-locking compound to apply to the fastener.

Thread Inserts
General purpose thread repair kits. These kits are available commercially.
| CAUTION | Refer to Safety Glasses Caution in Cautions and Notices. |
| IMPORTANT | Refer to the thread repair kit manufacturer's instructions regarding the size of the drill and tap to use. Avoid any buildup of chips. Back out the tap every few turns and remove the chips. |
Scheme 16
- Determine the size, the pitch, and the depth of the damaged thread. If necessary, adjust the stop collars on the cutting tool and tap to the required depth.
- Drill out the damaged threads. Clean out any chips.
- Lubricate the tap with light engine oil. Tap the hole. Clean the threads.
- Thread the thread insert onto the mandrel of the installer. Engage the tang of the insert onto the end of the mandrel.
- Lubricate the insert with light engine oil, except when installing in aluminum and install the insert.
- If the tang of the insert does not break off when backing out the installer, break the tang off with a drift.

Cutting Keys
After the code has been determined from the code list or the key code diagram, perform the following steps
- Cut a blank key to the proper level of each of the tumbler positions.
- Inspect the key operation in the lock cylinder.
Side Door Lock Cylinder Coding
The side door lock cylinder has five snap-in tumblers. The number 1-5 positions (beginning closest to the cylinder head) is a brass retainer tumbler. The 6-10 positions are standard tumbler positions. Therefore, only the 6-10 positions are required.
Lifting and Jacking the Vehicle
| CAUTION | To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed. |
| CAUTION | To avoid any vehicle damage, serious personal injury or death, always use the jackstands to support the vehicle when lifting the vehicle with a jack. |
