Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. When the dimensional style of the nut is not designated by the purchaser, hex nuts, Style 2, in conformance with ANSI B Please fill this form, we will try to respond as soon as possible. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This shall be the only hardness requirement for nuts that are proof load tested.

When this heat treatment is used, particular attention shall be paid to the requirements in 6. Purchasers are cautioned to consider the dimensional requirements of the application when selecting the most appropriate nut.

B Non-zinc-coated nuts are nuts intended for use with externally threaded fasteners which have a plain nonplated or noncoated finish or have a plating or coating of insufficient thickness to necessitate overtapping the nut thread to provide assemblability. Heat analysis Product analysis Nickel: Such nuts shall be tapped oversize to have internal threads with maximum and minimum limits that exceed the maximum and minimum limits specied for metric coarse internal threads with Grade 6H tolerances by the following diametral allowances: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The atmospheric corrosion resistance of these steels is substantially better than that of carbon steel with or without copper addition see 5. In addition, the manufacturer may add other distinguishing marks indicating that the nut is atmospheric corrosion resistant and of a weathering type.
