Scope
This document specifies the structure and dimensions of the MJ threaded twelve-sided self-locking nut with countersunk recesses for aerospace applications, with a strength grade of 1,100 MPa1/425℃2, 1,100 MPa1/650℃2, 1,210 MPa1/425℃2, 1,210 MPa1/730℃2, 1,550 MPa1/235℃2, 1,550 MPa1/425℃2, and 1,550 MPa1/600℃2.
1) When testing with bolts of the highest strength grade, the nut can withstand the minimum tensile strength load at ambient temperature without failure.
2) After the nut is subjected to the highest operating temperature, it will return to room temperature without permanently altering its original properties. The maximum operating temperature depends on the material or surface treatment condition of the nut.
This document is applicable to the design of the MJ threaded twelve-sided self-locking nut with countersunk recesses for aerospace applications (hereinafter referred to as the nut).
