Scope:

This specification covers established inch/pound manufacturing tolerances applicable to low-alloy steel bars ordered to inch/pound dimensions. These tolerances apply to all conditions, unless otherwise noted. The term "exclusive" is used to apply only to the higher figure 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.
