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).
