ASTM F436M PDF

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. Each type and style of washer shall be suitably sampled, and should conform to specified values of chemical composition, Rockwell hardness, inside and outside diameter, thickness, and clipped width. This abstract is a brief summary of the referenced standard.
