They are steel rods with one end having a slightly larger diameter than the other. Standard inch-sized taper pins have a taper on diameter of 1:48〔Machinery's Handbook〕 while metric ones have a taper of 1:50.〔Newnes Mechanical Engineer's Pocket Book〕 A 1:48 taper means that one end of a 4-foot-long bar (48 inches) will be 1 inch smaller in diameter than the other end, or a 1/4-inch taper over a 1-foot length. Some taper pins have a male screw thread on the small end that is designed to project through the hole and retain the pin with a washer and a nut. Other pins are threaded on both ends, on the thick end to pull the pin out with the same nut that holds the pin in place. Taper pin reamers are designed to prepare the hole for taper pins. Metric taper reamers are designated by the small diameter. For example, a 2 mm taper pin reamer has a 1.9 mm small end (2 mm nominal size) and a 2.86 mm large end.〔(Newman Tools Inc., metric taper pin reamers )〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Taper pin」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
