This is driving me crazy, the section modulus for Axis ZZ in the AISC tables 1-7 for single angles seems wrong.
They appear to be using Iz/c to get Sz but the "c" that they are using is wrong.
From what I understand, these Axis ZZ values are for the minor principal axis which is the weaker of the 2 (having a lower moment of inertia). They are using the C from the major principal axis and dividing that into the Iz from the minor principal axis.
I've attached a quick calc for the first angle in the tables, am I doing something wrong?
