INFORMATION
METRIC NUT IDENTIFICATION
1. A nut with an ISO metric thread is marked on
one face or on one of the flats of the hexagon
with the strength grade symbol 8, 12 or 14.
Some nuts with a strength 4, 5 or 6 are also
marked and some have the metric symbol M on
the flat opposite the strength grade marking.
2. A clock face system is used as an alternative
method of indicating the strength grade. The
external chamfers or a face of the nut is marked
in a position relative to the appropriate hour
mark on a clock face to indicate the strength
grade.
3. A dot is used to locate the 12 o’clock position
and a dash to indicate the strength grade. If the
grade is above 12, two dots identify the 12
o’clock position.
KEYS AND KEYWAYS
1. Remove burrs from edges of keyways with a fine
file and clean thoroughly before attempting to
refit key.
2. Clean and inspect key closely; keys are suitable
for refitting only if indistinguishable from new, as
any indentation may indicate the onset of wear.
TAB WASHERS
1. Fit new washers in all places where they are
used. Always fit a new tab washer.
2. Ensure that the new tab washer is of the same
design as that replaced.
SPLIT PINS
1. Fit new split pins throughout when replacing any
unit.
2. Always fit split pins where cotter pins were
originally used. Do not substitute spring
washers: there is always a good reason for the
use of a split pin.
3. All split pins should be fitted as shown unless
otherwise stated.
