8、a. 2.2 in General Data. 4 American National Standards Committee B18 for the standardization of bolts, screws, nuts, rivets and similar fasteners was organized in- March 1922, as Sectional Committee B18 under the aegis of the American Engineering Standards Committee (later the American Standards Asso
9、ciation, then the United States of America Standards Institute and, as of October 6,1969, the American National Standards Institute, Inc.), with the Society of Automotive Engineers and the American Society of Mechanical Engineers as joint sponsors. Subcornmitee 2 was subsequently established and cha
10、rged with the responsibility for technical content of stan- dards covering wrench head bolts and nuts. At its meeting on December 4, 1974, Committee B18 authorized preparation of a series of standards for metric fasteners. Subcommittee 2 was assigned responsibility for developing standards for metri
11、c hex bolts, screws and nuts. At a meeting on September 22, 1976, Subcommittee 2 organized the contents of a standard covering six different styles of hex nuts. Actual drafting was postponed until ISO/TC2 could reach final decisions relating to basic dimensions and characteristics of hex bolts, scre
12、ws and nuts. At ISO/TC2 meetings held in April 1977, final .actions were taken, Committee B18 affirmed the TC2 decisions at a meeting on June 29,1977, and draft- ing of this standard was started. In February 1978, Committee B18 established a cooperative program with the Department of Defense to draf
13、t American National Standards for metric fasteners in such a way that they could be used directly by the Government for procurement purposes. The Department of Defense requested that each of the six nut products be covered in separate standards, and Subcommittee 2 accepted this approach at its meeti
14、ng on June 27,1978. This standard was approved by letter ballot of Committee B18 on July 2, 1979, and was subsequently approved by the secretariats and submitted to the American National Standards Institute for designation as an American National Standard. This was granted on December 6, 1979. iii I
