6、utters, USAS B17f-1930, which standard was developed by subcbmmittee No. 5 of USA Standards Committee B17 on Shafting. The subcommittees initial work was started in 1925 and after nu- merous drafts and revisions was accepted by industry and designated by ASA (later changed to USASI) as an American S

7、tandard on December 31, 1930. The B17f-1930 standard was reaffirmed in 1955 but it was recognized that the standard was not in conformity with current practice. In 1962 the USA Standards Committee B17 was reactivated and a sub committee developed and established this updated standard on Woodruff Key

8、s and Keyseats which is in part a revision of B17f- 1930. Following approval by the USA Standards Committee B17 and the sponsor, the proposed revision was approved on September 18, 1967 by the USA Standards Institute, and redesignated B17.2-1967. USA STANDARD This USA Standard is one of nearly 3000

9、standards approved as American Standards by the American Standards Association. On August 24, 1966, the ASA was re- constituted as the United States of America Standards Institute. Standards approved as American Standards are now designated USA Standards. There is no change in their index identifica
