INSTALLATION
CAUTION: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that
application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners
that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other
corrosion Inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping
force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions
can help you avoid damage to parts and systems.
