The parts with aluminum or the cast iron washer surface/screw 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 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
