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”.

TIGHTENING TORQUE OF STANDARD BOLTS
The parts with aluminum or the cast iron washer surface/thread surface are excluded.
NEW STANDARD BASED ON ISO
CAUTION:
1. Use tightening torque with lubricant for the new standard bolts/nuts in principle. Friction coeffi-
cient stabilizer is applied to the new standard bolts/nuts.
2. However, use tightening to rque without lubricant for the foll owing cases. Friction coefficient stabi-
lizer is not applied to the following bolts/nuts.
- Grade 4.8, M6 size bolt, Co nical spring washer installed
- Paint removing nut (Size M6 an d M8) for fixing with weld bolt
