This specification covers established metric manufacturing tolerances applicable to low-alloy steel bars ordered to metric dimensions. These tolerances apply to all conditions, unless otherwise noted. The term "exclusive" is used to apply to the higher fatigue of the specified range. No clear cut demarcation is available to differentiate between bar and wire products, so no definitions of these products are included.
