ICS 21.060.10

PGD 37

Reaffirmed 2023

NATIONAL FOREWORD

This Indian Standard (Second Revision) which is identical with ISO 1482 : 2011 ‘Slotted countersunk (flat) head tapping screws’ 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.

This standard was originally published in 1974 and subsequently revised in 1989. The second revision of this standard has been undertaken to align it with the latest version of ISO 1482 published in 2011.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviation. Certain terminologies and conventions are, however, not identical to those used in the 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 decimal marker, while in Indian Standards, it is current practice to use a full point (.) as the decimal marker.
