Fastener Information
Metric Fasteners Information
Most of the fasteners used for this vehicle are JIS-defined and
ISO-defined metric fasteners. When replacing any fasteners, it is
most important that replacement fasteners be the correct diame-
ter, thread pitch and strength.
JIS-TO-ISO Main Fasteners Comparison Table
CAUTION:
Even when the nominal diameter (1) of thread is the
same, the thread pitch (2) or the width across flats (3)
may vary between ISO and JIS. Refer to JIS-TO-ISO Main
Fasteners Comparison Table below for the difference.
Installing a mismatched bolt or nut will cause damage to
the thread.
Before installing, check the thread pitch for correct
matching and then tighten it by hand temporarily. If it is
tight, recheck the thread pitch.
