One other notation on these motors... They have 4mm shaft..I was able to fashion a bushing to allow the 5mm to 8mm couplers by heat shrinking tubing to the shaft. turns out they are perfect fit now.

Received some great Nema 17 motors Yesterday. here are the specs.

These are nice 6 wire 1.8 degree stepper motors.
