13、 Metric Fastener Standards. The publication of this reference is a major milestone in a continuing IFI program toward engineering excellence both in manufacturing and application of fasteners and custom formed parts. The content of this publication is based on an IFI decision in 1971 to take a leade
14、rship position in an effort to develop a globally acceptable sys- tem of metric engineering standards for mechanical fasteners which would be highly efficient and offer significant improvements for fastener users and producers alike. Working initially as an ANSI Study Committee and then under the co
15、nsensus standards organizations including ASME, SAE and ASTM, a completed system is now available. The members of IFI hope that you will find within the pages of the Third Edition a wealth of information which will help in the design, selection and assembly of the many products needed in our globall

17、 THIRD EDITION OF METRIC FASTENER STANDARDS This book is divided into 12 sections including 8 product sections and 4 sections which contain screw threads and gaging practices, materi- als, technical data and quality assurance. A divider page at the beginning of each section contains its table of con
18、tents. Each section is a letter of the alphabet and each page carries the section letter designation and a number as A- 1, B- 2, C- 4, etc. A subject index is found on the last pages of this book. Major head- ings are shown in bold type. These headings will help readers quickly lo- cate reference ma
19、terial. For example, under cap screws the reader will find various styles, mechanical properties, test methods, and weights together with other related information. A few minutes examining this index organi- zation will be a real time saver in seeking the information you may need. It is recommended
20、that the reader examine the terminology which begins on page K- 37. A solid understanding of basic terms which are com- monly used will reduce confusion and enhance understanding. Finally and most importantly, the reader should understand that stan- dards are living documents which are constantly un
21、der review and possible revision. Changes are usually the result of experience which indicates that a change(s) is desirable. The standards included are presented at a given point in time. If the issue or date of the most current standard is important, it is recommended that the issuing organization
22、 be contacted to confirm the latest date or revision status. 本文件原文页数过多,体积过大,无法上传。 如有需要请发站内信或e m a i l :l i u y x 866163.c o m 联系人:草庐一苇:w w w .d o c i n .c o m /l i u y x 866 CAUTIONARY NOTES AND DISCLAIMERS All users of the standards published in this book are cautioned that such standards may be re

25、s and a description of each organization is included in Section K. All standards, specifications, technical discussions, and reports included in this book are advisory only and their use by anyone is entirely voluntary. Reliance on their contents for any purpose by anyone is at the sole risk of that
26、 person and IFI is not responsible for any loss, claim or damage arising therefrom. In compiling this book, IFI has made a determined effort to present its contents accurately.

27、I has not investigated, nor will it investigate, patents which may apply to the subject con- tents. Prospective users of this book are responsible for advising themselves and protecting themselves against any patent infringement liability which may arise out of such use. COMMENTS AND SUGGESTIONS Sin
28、ce issuance of the first edition of this book in 1976, many indi- viduals have offered constructive ideas and suggestions on means for im- proving the content and its presentation. All of these have been most help- ful in the preparation of each successive edition and IFI appreciates the interest an
29、d the input. Readers are invited to continue submitting their com- ments and IFI assures that all comments will be considered.

40、.d o c i n .c o m /l i u y x 866 METRIC SCREW THREADS IFI NOTE: At New Delhi, India in 1964, an historic meeting of ISO Technical Committee 1 (TC1) produced final agreements for all tolerances and allowances for a metric screw thread profile and a full range of pitch- diameter combinations. Subseque
41、ntly, OMFS (Optimum Metric Fastener System) proposals were submitted by North America and a compromise approved by IS0/TC1 at Stockholm in 1976. Following this accord ASME Standards Committee B1 initiated development of a metric screw threads - M profile standard which was first published in 1979, a
42、nd designated ANSI/ASME B1.13M. This standard was in basic agreement with the Stockholm accord and provided a system of metric screw threads and detailed information for diameter- pitch combinations. Since 1979, a new issue dated 1983 has been published and a second revision dated 1994 is included i
43、n this section. SCREW THREADS I SCREW THREAD CHARACTERISTICS IFI has prepared an introduction to this section to explain in “layman“ terms some concepts which will assist in a fuller understanding of screw threads. While various forms of threads have ex- isted for almost all of recorded history, it
44、was not until Archimedes that the first known practical application of the screw thread was confirmed. His study developed the means of raising water from one level to another by using the basic screw thread form and helped foster irrigation. Since that time screw threads have evolved into extremely
45、 useful forms. To become reasonably thread friendly, a person must become familiar with about 30 basic terms. (Experts probably relate to 125 or more features or characteris- tics.) A screw thread is a ridge of uniform sec- tion in the form of a helix on the external or inter- nal surface of a cylin
46、der. A thread formed on a cylinder is called a straight or parallel thread, while that formed on a cone or frustum of a cone is called a tapered thread. External threads are threads on bolts, screws and studs. Internal threads are those in nuts or tapped holes. The thread form or profile in an axial
47、 plane is made up of three elements: the roof, cresf and flank. The root is at the bottom of the groove and is joined to the crest, which is at the top of the ridge, by the flank. The fundamental triangle is that formed when the profile is ex- tended to a sharp V at both crest and root. The height o
48、f the fundamental triangle (H) is the dis- tance measured radially between the sharp crest and sharp root diameters; see Fig. 1 of B1.13M on page A- 21. For 60 metric threads - M pro- file H equals 0.866 0254 times thread pitch (com- piled in Table 3, A- 27.) The height of screw threads is controlle
49、d by the amount of trunca- tion at the crest and root of the fundamental tri- angle with the basic M profile thread height at 0.625H or 0.541 266P. On an external thread, the diameter at the thread crests is the major diameter, and at its thread roots is the minor diameter. On an internal thread, it is the opposite; the diameter 本文件原文页数过多,体积过大,无法上传。 如有需要请发站内信或e m a i l :l i u y x 866163.c o m 联系人:草庐一苇:w w w .d o c i n .c o m /l i u y x 866 SCREW THREADS METRIC SCREW THREADS I at the crests is the minor diameter and at the roots the m
