Organization: ASTM
Publication Date: 1 December 2019
Status: active
Page Count: 8
ICS Code (Nuts): 21.060.20
scope:

This specification covers the chemical, mechanical, and dimensional requirements for hardened steel washers for use with fasteners having nominal thread diameters of 14 through 4 in. and M12 through M100. These washers are intended for general-purpose mechanical and structural use with bolts, nuts, studs, and other internally and externally threaded fasteners. These washers are suitable for use with fasteners covered in Specifications A354, A449, A563, A563M, F959/F959M, and F3125.

The washers are designated by type denoting the material, by style denoting the shape, and by inch or metric dimensions.

The types of washers covered are:

Type 1-Carbon steel.

Type 3-Weathering steel.

This specification provides for furnishing Type 3 to chemical composition or a Corrosion Index (CRI) of 6 or higher at the suppliers option.

The styles of washers covered are:

Circular-Circular washers in nominal sizes 14 through 4 in. and M12 through M100 suitable for applications where sufficient space exists and angularity permits.

Beveled-Beveled washers are square or rectangular, in nominal sizes 12 through 112 in., M12 through M16, with a beveled 1 to 6 ratio surface for use with American standard beams and channels.

Clipped-Clipped washers are circular or beveled for use where space limitations necessitate that one side be clipped.

Extra Thick-Extra thick washers are circular washers in nominal sizes 12 through 4 in., with a nominal thickness of 516 in. suitable for structural applications with oversized holes.

Terms used in this specification are defined in Terminology F1789 unless otherwise defined herein.

The values stated in either inch-pound units for inch fasteners and SI units for metric fasteners and are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

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.
