1.1 This specification covers the chemical, mechanical, and dimensional requirements for hardened steel washers for use with fasteners having nominal thread diameters of 1\/4 through 4 in. 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 A 325, A 354, A 449, A 490, and A 687.<\/p>\n
1.2 The washers are designated by type<\/i> denoting the material and by style<\/i> denoting the shape.<\/p>\n
1.2.1 The types of washers covered are:<\/p>\n
1.2.1.1 Type 1<\/i> Carbon steel.<\/p>\n
1.2.1.2 Type 3Weathering steel. Atmospheric corrosion resistance and weathering characteristics are comparable to that of steels covered in Specifications A 588\/A 588M and A 709\/A 709M. The atmospheric corrosion resistance of these steels is substantially 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.<\/p>\n
1.2.2 The styles of washers covered are:<\/p>\n
1.2.2.1 CircularCircular washers in nominal bolt sizes 1\/4 through 4 in. suitable for applications where sufficient space exists and angularity permits.<\/p>\n
1.2.2.3 Beveled<\/i> Beveled washers are square or rectangular, in nominal sizes 1\/2 through 1 1\/2 in., with a beveled 1 to 6 ratio surface for use with American standard beams and channels.<\/p>\n
1.2.2.3 Clipped<\/i> Clipped washers are circular or beveled for use where space limitations necessitate that one side be clipped.<\/p>\n
Note 1A complete metric companion to Specification F 436 has been developed-Specification F 436M; therefore no metric equivalents are presented in this specification.<\/p>\n
