b.
To help mechanics know when metric fasteners are used on a product, future service publications such as parts
books and operation/maintenance manuals will use a notice similar to the one that follows:
NOTICE
CAUTION MUST BE TAKEN TO AVOID MIXING METRIC AND INCH (CUSTOMARY)
FASTENERS. MISMATCHED OR INCORRECT FASTENERS CAN RESULT IN EQUIPMENT
DAMAGE OR MALFUNCTION, OR POSSIBLE PERSONAL INJURY. ORIGINAL FASTENERS
REMOVED FROM THE VEHICLE SHOULD BE SAVED FOR ASSEMBLY WHEN POSSIBLE. IF
NEW FASTENERS ARE REQUIRED, CAUTION
MUST BE TAKEN TO REPLACE THE FASTENER WITH ONE THAT IS OF THE SAME
SPECIFICATIONS (SIZE/GRADE) AS THE ORIGINAL.
c.
To convert inches to millimeters, or millimeters to inches, see The Metric System And Equilavents (inside back
cover).
