Compared to standard hex nuts, square nuts have a greater surface in contact with the part being fastened, and therefore provide greater resistance to loosening (though also greater resistance to tightening). They are also much less likely to become rounded-off after repeated loosening/tightening cycles. Square nuts are typically mated with square-headed bolts. Square nuts are used along with flat washers in order to avoid damage from its sharp edges and helps to increase the strength of the fastener. ==History== Early nuts were made of wood and were used with wooden pegs. The square shape made it possible to form a tool in order to tighten nut in place. Later wooden fasteners were replaced by steel ones, and modern nuts are forged from steel stock bars and used along with steel bolts. Square steel nuts were common on machinery of the late 19th through mid 20th century. Today hex nuts have displaced them. One reason is that a hex nut offers a new wrenching access at every 60°, whereas a square nut offers one only at every 90°. 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「Square nut」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.
