ASTM F436 Structural Washers
These washers are intended for general-purpose mechanical and structural use with bolts, nuts, studs, and other internally and externally threaded fasteners. The types of washers covered here are: Type 1—washers made of carbon steel; and Type 3—washers made of weathering steel. Moreover, the styles of washers covered here are: circular washers, which are suitable for applications where sufficient space exists and angularity permits; beveled washers, which are square and rectangular with a beveled surface for use with American Standard beams and channels; and clipped washers, which are circular or beveled for use where space limitations necessitate that one side be clipped. Steels to be used to manufacture the washers shall be produced by the open-hearth, basic-oxygen, or electric-furnace process.
F436 Hardened Washers
Permissions to reprint documents can be acquired through Copyright Clearance Center ASTM License Agreement Withdrawn Rationale: This specification covers the chemical, mechanical, and dimensional requirements for metric hardened steel washers for use with fasteners having nominal thread diameters M12 through M Scope 1. These washers are intended for general-purpose mechanical and structural use with bolts, nuts, studs, and other internally and externally threaded fasteners. The atmospheric corrosion resistance of these steels is substantially better than that of carbon steel with or without copper addition. See 5.
