IS 15469 : 2024/ISO 3185 : 2021 Aerospace - Bolts, Normal Bihexagonal Head, Normal Shank, Short or Medium Length MJ Threads, Metallic Material, Coated or Uncoated, Strength Classes Less Than or Equal to 1 100 MPa - Dimensions
NATIONAL FOREWORD
This Indian Standard (Second Revision) which is identical to ISO 3185 : 2021 ‘Aerospace - Bolts, normal bihexagonal head, normal shank, short or medium length MJ threads, metallic material, coated or uncoated, strength classes less than or equal to 1 100 MPa - Dimensions’ issued by International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on the recommendation of the Air and Space Vehicles Sectional Committee and approval of the Transport Engineering Division Council.
This standard was first published in 2004. The first revision of this standard has been undertaken with a view to bring it in line with the version of ISO 3185 : 2008. Second revision of this standard is undertaken to align it with the latest version of ISO 3185 : 2021.
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’; and
b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
