Torque of a stepper motor is entirely independent from the microstepping setting. In fact, currents flowing through motor coils are identical after one full step vs. after 16 microsteps at 1/16.

The Arduino source for this can be found on the project GitHub. Whilst [Frank] mentions that this assembly has a weight and torque advantage over a NEMA 17 sized stepper motor, ...
