ASTM WK43065

    New Specification for High Strength Structural Bolts, Steel and Alloy Steel, Heat Treated, 120ksi (830MPa) and 150ksi (1040MPa) Minimum Tensile Strength, Inch and Metric Dimensions

    (What is a Work Item?)

    Developed by Subcommittee: F16.02 | Committee F16 | Contact Staff Manager


    1. Scope

    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.


    bolts; alloy steel; carbon steel; metric; inch; steel; structural bolts; weathering steel; alternate design fasteners; fasteners; spline end; tension control bolt; twist-off bolt, heavy hex bolt

    The title and scope are in draft form and are under development within this ASTM Committee.
