Andrew, They are the same, although for a washer or lockwasher, the 4-40 is a misnomer, the #4 designation for the hole size is correct, but the -40 refers to the thread pitch, and there are no threads in a washer. Just for additional information, most of the screw hardware in the K3 is 4-40 although there are a few 2-56 size. There is a big difference in the diameter, so you are not likely to mix the two.
