This International Standard specifies the characteristics of bolts for pulleys with thin hexagonal head, close tolerance shank and short thread, -- in alloy steel and cadmium plated, classification 1 100 MPa 1) /235 oC 2) ; -- in titanium alloy and MoS2 lubricated, classification 1 100 MPa 1) /315 oC 2) ; or -- in corrosion-resistant steel and passivated. This International Standard is applicable to bolts used with ISO 9217 and ISO 9218 washers, ISO 9216 nuts and ISO 1234 split pins. 1) Minimum tensile strength of the material and passivated at ambient temperature. 2) Maximum temperature, determined by the surface treatment, that the bolt can withstand without continuous change in its original characteristics after return to ambient temperature.
