ASTM-F436 › Standard Specification for Hardened Steel Washers Inch and Metric Dimensions
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
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 A325, A354, A449, A490, and A687.
1.2 The washers are designated by type denoting the material and by style denoting the shape.
1.2.1 The types of washers covered are:
188.8.131.52 Type 1 --Carbon steel.
184.108.40.206Type 3 -Weathering steel. Atmospheric corrosion resistance and weathering characteristics are comparable to that of steels covered in Specifications A588/A588M and A709/A709M. 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.
1.2.2 The styles of washers covered are:
220.127.116.11 Circular --Circular washers in nominal bolt sizes 1/4 through 4 in. suitable for applications where sufficient space exists and angularity permits.
18.104.22.168 Beveled--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.
22.214.171.124 Clipped -Clipped washers are circular or beveled for use where space limitations necessitate that one side be clipped.
Note 1--A complete metric companion to Specification F436 has been developed-Specification F436M; therefore no metric equivalents are presented in this specification.
