FASTENERS
The materials and designs
of
the various
fa
steners used on
yo
ur Suzuki are not arrived at
by chance or accident.
Fa
stener design determines
the
type
of
lool required to work the
fas
tener. Fas-
tener material is carefully selected to decrease the
possibility
of
physical failure.

Nuts. bolls a
nd
screws arc manufactured
in
a
wide range of thread pallcrns. To join a
nu
t and
bolt. the diameter of the bolt and the diameter
of
the hole
in
the
nUl
mu
st
be
the same. It is
ju
st as
important that the threads on both
be
properly
matched .
The best way to tell
if
the threads on 2
fas
teners
are matched
is
to turn the n
Ul
on the bo
lt
(or
the
bolt into
th
e threaded hole in the piece
of
equipment), with your fingers o
nl
y.
Be sure both
pieces
are
clean.
If
much force
is
required. check
the thread co
nd
ition on each fastener. If the thread
condition
is
good. but the
fas
tener
jam
s. the threads
are not compatible. A thread pitch gauge (
Figure
7) can also
be
used to determine pitch. Suzuki
motor
cycl
es are manufactured with metric standard
fastener
s.
The threads are c
ut
differently than those
of
American fasteners (
Figu
re 8).
Most th reads
are
cut so that the fastener must
be turned
clockwise to tighten it. These
are
ca
ll
ed
right·hand threads. Some fasteners have left-hand
threads; they must be turned coumerclockwise to
be tightened. Left·hand
thr
eads
are
used
in
locations where n
or
mal rotation of the equipment
would tend to loosen a r
ig
ht-hand threaded fasten-
er. When left-hand
thr
eads are u
se
d

CHAPTER ONE
Machi
ne Screws
There arc many different types
of
machine
screws. Fig
ur
e 9 shows a number
of
scr
ew
heads
requiring
diff
erent types of turning tool
s.
Heads
are
also designed to protrude above the metal
(round
or
hex)
or
to
be
s
li
gh
tl
y recessed
in
th
e mel-
al
(nat). See
