NATIONAL FOREWORD

This Indian Standard (Part 3) (First Revision) which is identical with ISO 898-1 : 2013 ‘Mechanical properties of fasteners made of carbon steel and alloy steel — Part 1 : Bolts, screws and studs’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the General Engineering and Fasteners Standards Sectional Committee and approval of the Production and General Engineering Division Council.

IS 1367 which covers the ‘Technical supply conditions for threaded steel fasteners’ was originally published in 1961 and first revised in 1967. In the late seventies, the second revision was taken up when the work of ISO/TC 2, ‘Fasteners’ taken into consideration of our national work on industrial fasteners. Accordingly, the Committee decided that IS 1367 should be brought out into several parts, each part covering a particular feature or property of the fasteners. Subsequently, the second revision of this standard was published in 1979. The third revision was published in 1991 by adoption of ISO 898-1 : 1988 and the fourth revision was done by adoption of ISO 898-1:1999 published in 1999. This fifth revision has been prepared by adoption of latest edition of ISO 898-1 published in 2013.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain 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’.

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.
