GRADES 2.1 Steel for spring washers shall be ofsix grades as specified in Table 1. 3. SUPPLY OF MATERIAL 3.1 General requirements relating to the supply of material

The type and magnitude of the load to which a spring washer will be sub-jected and the reactive force it will be required to exert are the primary factors that determine the type of spring washer best suited to a specific application. This range of deflection,or "spring travel",is an important element of spring washer design.

This standard covers requirements for spring lock washers suitable for use with bolt/nut assemblies involving fasteners of property classes less than 8.8 in the size range 2 to 48 mm. 2 REFERENCES The following Indian Standards are necessary adjuncts to this standard: ZS No.
