12.1 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 E29.

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 0.250 to 1.500 in. and socket head cap screws (including socket head cap, button head and flat countersunk head configurations) with nominal thread 0.06 (size 0) through 1.500 in. inclusive in diameter manufactured from a number of alloys in common use and intended for general service applications.

1.2 Applicable nuts for use with bolts, cap screws, and studs covered by this specification are covered by Specification F467.

1.2.1 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

Note 1: A complete metric companion to Specification F468 has been developed—F468M; therefore no metric equivalents are presented in this specification.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
