螺紋簡介： 1.1螺紋的起源 一般認為，阿基米德（公元前287-212年）是首先將螺紋用于工業目的，即將低處的水移到高處的一種工具。 1659年法國人貝茲遜發明螺紋切割機；其后，經過英國的威阿特、亨利?莫斯列，到其子弟約瑟夫?惠氏于1841年才 統一原本混亂的螺紋，促進螺紋制品的全球普及；因此，惠氏螺紋也隨英國工業的發達而廣泛傳播世界。 美制螺紋依據塞勒氏螺紋（seller'sthread）而問世于1924年；二次世界大戰中，美國、英國、加拿大三國協 定發展成統一制螺紋unifiedthread。隨著國際交流的頻繁，1947年成立的iso國際標準化組織（internationalstandard organization)成為推動國際標準化的重要力量。 1.2螺紋概述 按用途分類，可分為緊固螺紋、密封螺紋、傳動螺紋、管螺紋、專用螺紋。 1.3螺紋的分
