Abstract / scope

ISO 9157:2002 specifies the dimensions of spline-drive nuts, with MJ threads and a self-locking feature achieved by forming the upper portion out-of-round, for classifications: 1 100 MPa/425 °C, 1 100 MPa/650 °C, 1 210 MPa/425 °C, 1 210 MPa/730 °C, 1 550 MPa/235 °C, 1 550 MPa/ 425 °C and 1 550 MPa/600 °C.

ISO 9157:2002 is only applicable for the compilation of aerospace product standards.
