Areas for Calculating Stress or Load Values for Metric MJ Externally Threaded Fasteners(STABILIZED May 2019)
MA1520B
Areas for the standard metric series of thread diameter-pitch combinations for aerospace externally threaded fasteners are established for the following conditions:
a
Area for ultimate shear stress or load in unthreaded shank.
b
Area for ultimate tensile stress or load in thread.
c
Area for stress durability test load in thread.
d
Area for stress-rupture test load at elevated temperature.
