Nails, whose real name was Joe Snyder, was a Boston native connected with the Winter Hill gang.Snyder had been given the nickname Nails by the professional gamblers in Las Vegas, for his tenacity in dealing with point spreads on sports betting.He was considered "hard as nail" for never taking the worst of a point spread on ant gambling event.If Joe favored betting on a game at one particular point spread,and the number was not available,he would not make the bet.By Domenic Spinale
