TIGHTENING TORQUE OF STANDARD BOLTS

TIGHTENING TORQUE OF STANDARD BOLTS

Description

INFOID:0000000009480208

This vehicle has both new standard based on ISO* and previous 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-18, "Tightening Torque Table (New Standard Included)"

• If the tightening torque is not described in the description or figure, refer to

GI-18, "Tightening Torque Table

(New Standard Included)"

*ISO: International Organization for Standardization

Tightening Torque Table (New Standard Included)

INFOID:0000000009480209

CAUTION:

• The special parts are excluded.

• The bolts/nuts in these tables have a strength (discrimination) number/symbol assigned to the head

or the like. As to the relation between the strength grade in these tables and the strength (discrimi-

nation) number/symbol, refer to “DISCRIMINATION OF BOLTS AND NUTS”.

PREVIOUS STANDARD

CAUTION:

The parts with aluminum or the cast iron washer surface/thread surface are excluded.

TIGHTENING TORQUE OF STANDARD BOLTS

GI-19

< HOW TO USE THIS MANUAL >

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 torque without lubricant for the following cases. Friction coefficient stabi-

lizer is not applied to the following bolts/nuts.

Grade 4.8, M6 size bolt, Conical spring washer installed

Paint removing nut (Size M6 and M8) for fixing with weld bolt
