The chief requirements of a good screw-calk are, further, a clean, deep, but not too coarse thread, and but one size of thread and tap for all calks, so that every calk will fit in every shoe. A calk whose tap measures one- half inch ( millimetres) in diameter is sufficient for the heaviest shoes. In the German army the calks used have a tap fifteen thirty-seconds of an inch in diameter. The coachman should be given four calks (sharp. Sharp screw-calks with Whitworth thread (half-inch, natural size).
