O PTIGHTENING TORQUE OF STANDARD BOLTS
DescriptionINFOID:0000000006280848
This vehicle has both new standard based on ISO* and prev ious standard bolts/nuts. There are some differ-
ences between these two types of bolts/ nuts; shape of the head, grade of strength, hexagonal width across
flats and the standard tightening torque.
For guidance in discriminating, refer to GI-19, "
Tightening Torque Table (New Standard Included)".
The new standard machine screws and tapping screws have a head of ISO standard torx recess.
If the tightening torque is not described in the description or figure, refer to GI-19, "
Tightening Torque Table
(New Standard Included)".
*ISO: International Organization for Standardization
Tightening Torque Table (New Standard Included)INFOID:0000000006280849
CAUTION:
The special parts are excluded.
The bolts/nuts in these tables have a strength (d iscrimination) number/symbol assigned to the head
or the like. As to the relation between the streng th grade in these tables and the strength (discrimi-
nation) number/symbol, refer to “DISCRIMINATION OF BOLTS AND NUTS”.
