nails
 n.pl.— «After learning the game on plastic cleats, most golfers stick with them as they turn pro. Often referred to as “nails” by players and suppliers, metal spikes are permitted throughout Europe and at a handful of courses in the U.S. Pacific Northwest. Wet weather in those regions make the metal spikes more effective, players say, because they are longer.» —“Another Thing Woods Can Do That You Can’t: Wear Metal Spikes” by Michael Buteau Bloomberg.com Aug. 10, 2007.
