1、Designation: F436 11F436/F436M 16Standard Specification forHardened Steel Washers Inch and Metric Dimensions1This standard is issued under the fixed designation F436;F436/F436M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the y
2、ear of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification cover
3、s the chemical, mechanical, and dimensional requirements for hardened steel washers for use withfasteners having nominal thread diameters of 14 through 4 in. and M12 through M100. These washers are intended forgeneral-purpose mechanical and structural use with bolts, nuts, studs, and other internall
4、y and externally threaded fasteners. Thesewashers are suitable for use with fasteners covered in Specifications A325, A354, A449, and A490F3125.1.2 The washers are designated by type denoting the material and material, by style denoting the shape.shape, and by inch ormetric dimensions.1.2.1 The type
5、s of washers covered are:1.2.1.1 Type 1Carbon steel.1.2.1.2 Type 3Weathering steel. Atmospheric corrosion resistance and weathering characteristics are comparable to that ofsteels covered in Specifications A588/A588M and A709/A709M. The atmospheric corrosion resistance of these steels issubstantiall
6、y better than that of carbon steel with or without copper addition. See 5.1. When properly exposed to the atmosphere,these steels can be used bare (uncoated) for many applications.1.2.1.3 This specification provides for furnishing Type 3 to chemical composition or a Corrosion Index (CRI) of 6 or hig
7、her atthe suppliers option.1.2.2 The styles of washers covered are:1.2.2.1 CircularCircular washers in nominal bolt sizes 14 through 4 in. and M12 through M100 suitable for applications wheresufficient space exists and angularity permits.1.2.2.2 BeveledBeveled washers are square or rectangular, in n
8、ominal sizes 12 through 112 in., M12 through M16, with abeveled 1 to 6 ratio surface for use with American standard beams and channels.1.2.2.3 ClippedClipped washers are circular or beveled for use where space limitations necessitate that one side be clipped.1.2.2.4 Extra ThickExtra thick washers ar
9、e circular washers in nominal sizes 12 through 1412 in., with a nominal thicknessof 516 in. suitable for structural applications with oversized holes.1.3 Terms used in this specification are defined in Terminology F1789 unless otherwise defined herein.1.4 The values stated in inch-pound units either
10、 inch-pound units for inch fasteners and SI units for metric fasteners and are tobe regarded as standard. No other units of measurement are included in this separately as standard.The values stated in each systemmay not be exact equivalents; therefore, each system shall be used independently of the
11、other. Combining values from the twosystems may result in non-conformance with the standard.NOTE 1A complete metric companion to Specification F436M has been developedSpecification F436M; therefore no metric equivalents arepresented in this specification.1.5 This standard does not purport to address
12、 all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.1 This specification is under the jurisdiction of ASTM Committ
