The word appears in Angus's line in V, 6, "Now minutely revolts upbraid his faith-breach;" To upbraid is to chastise, admonish or scold. That's the easy word. "Faith-breach" is a word Shakespeare made up, but we can guess that it means his breach of faith in murdering Duncan. "Revolts" are challenges to his authority. "Minutely" generally means in small details. So we get "Now in small details challenges to his authority scold him for his breach of faith." as the meaning of the line.
In Macbeth, when Lady Macbeth tells Macbeth to "screw your courage to the sticking point and we'll not fail," she is essentially urging him to gather his courage and determination to a fixed point like a screw. This means to steel himself mentally and be resolute in carrying out their plan.
