Foreword This translation has been made based on the original Japanese Industrial Standard revised by the Minister of Economy, Trade and Industry through deliberations at the Japanese Industrial Standards Committee, as the result of proposal for revision of Japanese Industrial Standard submitted by The Japan Research Institute for Screw Threads and Fasteners (JFRIYJapanese Standards Association (JSA) with the draft being attached, based on the provision of Article 12 Clause 1 of the Industrial Standardization Law applicable t o the case of revision by the provision of Article 14. Consequently JIS B 1180 : 2001 is replaced with this Standard. In order to conform t o the International Standards, this revision has been prepared based on I S 0 4014 : 1999 Hexagon head bolts-Product grades A and B , I S 0 4015 : 1979 Hexagon head bolts-Product grade B-Reduced shank (shank diameter approximately equal to pitch diameter), I S 0 4016 : 1999 Hexagon head bolts-Product grade C,IS0 4017 : 1999 Hexagon head screwsProduct grades A and B , I S 0 4018 : 1999 Hexagon head screws-Product grade C , IS0 8676 : 1999 Hexagon head screws with metric fine pitch thread-Product grades A and B and I S 0 8765 : 1999 Hexagon head bolts with metric fine pitch thread-Product grades A and B . Attention is drawn t o the possibility that some parts of this Standard may conflict with a patent right, application for a patent after opening to the public, utility model right or application for registration of utility model after opening to the public which have technical properties. The relevant Minister and the Japanese Industrial Standards Committee are not responsible for identifying the patent right, application for a patent after opening to the public, utility model right or application for registration of utility model after opening t o the public which have the said technical properties.

Introduction This Japanese Industrial Standard has been prepared based on the third edition of IS0 4014 : 1999 Hexagon head bolts-Product grades A and B published in 1999, the first edition of IS0 4015 : 1979 Hexagon head bolts-Product grade B-Reduced shank (shank diameter approximately equal to pitch diameter) published in 1979, the third edition of I S 0 4016 : 1999 Hexagon head bolts-Product grade C , I S 0 4017 : 1999 Hexagon head screws-Product grades A and B , I S 0 4018 : 1999 Hexag o n head screws-Product grade C published in 1999, the second editions of I S 0 8676 : 1999 Hexagon head screws with metric fine pitch thread-Product grades A and B , and I S 0 8765 : 1999 Hexagon head bolts with metric fine pitch thread-Product grades A and B published in 1999, by integrally editing corresponding parts thereof (shapes and dimensions, product specification and designations) without modification in technical contents.
The hexagon head bolts not in accordance with IS0 4014 to IS0 4018, I S 0 8676 and I S 0 8765 are specified in annex 1 with clarified term of withdrawal. 1 Scope This Standard specifies the hexagon head bolts and hexagon head screws made of steel, stainless steel and non-ferrous metals. If there are any requirements other than the dimensions and product specification specified in this Standard, those requirements should be selected from, for example, JIS B 0205-4, JIS B 0209-1, JIS B 1003, JIS B 1009, JIS B 1021, JIS B 1051 and JIS B 1054-1.
Remarks 1 Hexagon head bolts not in accordance with the text of this Standard shall be in accordance with annex 1 (normative).
2 The International Standards corresponding t o this Standard are as follows. In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standards and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according t o ISO/IEC Guide 21.
