For purposes of determining compliance with the specified limits for requirements of the properties listed in this specification, an observed value or calculated value shall be rounded in accordance with Practice E 29.

This specification covers the requirements for commercial wrought nonferrous bolts, hex cap screws, and studs manufactured from a number of alloys in common use and intended for general service applications. The bolts, cap screws, and studs shall be manufactured from material having a chemical composition conforming to the requirements specified. The fasteners shall be cold formed, hot formed, or machined from suitable material. Different tests shall be conducted in order to determine the following mechanical properties of fasteners: hardness, tensile strength, yield strength, and elongation.

1.1 This specification covers the requirements for commercial wrought nonferrous bolts, hex cap screws, and studs in nominal thread diameters M6 to M36 inclusive manufactured from a number of alloys in common use and intended for general service applications.

1.2 Unless otherwise specified, nuts used on these bolts, cap screws, and studs shall conform to the requirements of Specification F 467M. Nuts shall be of the same alloy group as the fastener on which they are used and shall have a specified minimum proof stress equal to or greater than the specified minimum tensile strength stress of the fastener on which they are used.

Note 1—This specification is the metric companion of Specification F 468.
