Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 3) (First Revision) which is identical with ISO 965-3 : 2021 ‘ISO general purpose metric screw threads - Tolerances - Part 3: Limit deviations for screw threads’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the General Engineering and Fasteners Standards Sectional Committee and approval of the Production and General Engineering Division Council.

The various requirements of ISO general purpose metric screw threads except tolerances; are covered under IS 4218 (Part 1 to 4). The tolerances were earlier covered under IS 4218 (Part 5 and 6) which were then superseded by IS 14962 (Part 1 to 5) in 2001.
