This Standard specifies the determination method of the target values of tighten-
ing index for threaded fasteners in the representative tightening control method and
the related matters to this.
This Standard shall apply to bolts, machine screws, studs (hereafter these are re-
ferred to as "bolts") and nuts made of carbon steel and alloy steel. This Standard is
also applicable to other combination of external and internal thread parts having the
general purpose metric screw threads of the basic profile based on JIS B 0205-1.
This Standard may not apply to the studded side of stud bolts, set screws and similar
threaded fasteners not under tensile stresses, threaded fasteners forming profile of
internal threads by external threads themselves and threaded fasteners having the
additional whirl-stop function.
