This specification covers chemical, physical and mechanical requirements for quenched and tempered bolts manufactured from steel and alloy steel, in metric and inch dimensions, in two strength grades, two styles and two types. This specification is a consolidation and replacement of six ASTM standards, including; A325, A325M, A490, A490M, F1852 and F2280.
This consolidated standard is to ensure alignment between standards with the same intended end use and to simplify the use and maintenance of structural bolt specifications. Users will be fastener manufacturers, engineers, detailers, steel fabricators and inspectors.
