Etymologies

Middle English skrewe, from Old French escrove, female screw, nut, perhaps from Medieval Latin scrōfa, from Latin, sow
(American Heritage® Dictionary of the English Language, Fourth Edition)
From Middle English screw, scrue ("screw"); apparently, despite the difference in meaning, from Old French escroue ("nut, cylindrical socket, screwhole"), of uncertain origin. There is also the Old French escruve ("screw"), from Old Dutch *scrūva ("screw"; whence Middle Dutch schruyve ("screw")), which probably influenced or conflated with the aforementioned resulting in the Middle English word. (Wiktionary)
