IS 1367 : Part 10 : 2002/ISO 6157-2 : 1995 Technical Supply Conditions for Threaded Steel Fasteners - Part 10 : Surface Discontinuities - Nuts

National Foreword

This Indian Standard ( Part 10 ) ( Third Revision ) which is identical with ISO 6157-2:1995 ‘Fasteners - Surface discontinuities - Part 2: Nuts’ issued by the International organization for Standardization ( ISO ) was adopted by the Bureau of Indian Standards on the recommendation of the Bolts, Nuts and Fasteners Accessories Sectional Committee and approval of the Basic and Production Engineering Division Council.

The concerned Technical Committee has reviewed the Scope of this particular standard and decided that application of this standard may be extended to ‘Product Grade C’ products also.

This standard was originally published in 1961 and subsequently revised in 1967 and 1979. The last revision was based on lSO/DIS 61 57/11-1979. Consequent upon revision of IS 6157-2 the Sectional Committee decided to revise this standard aligning with ISO 6157-2:1995 by adoption under dual numbering system.

The text of ISO Standard has been approved as suitable for publication as Indian Standard without deviations. Certain terminology and conventions are, however, not identical to those used in the Indian Standards. Attention is drawn especially 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.
