NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 8765:1999 ‘Hexagon head bolts withmetric fine pitch thread — Product grades A and B’ issued by the International Organization for

Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of theBolts, Nuts and Fasteners Accessories Sectional Committee and approval of the Basic and ProductionEngineering Division Council.

This standard was originally published in 1994 by adoption of ISO 8765:1988. This first revision hasbeen made by adoption of the latest edition of ISO 8765 published in 1999.

The text of ISO Standard has been approved as suitable for publication as Indian Standard withoutdeviation. Certain terminology and conventions are, however, not identical to those used in the IndianStandards. Attention is drawn especially to the following:

a) Wherever the words ‘International Standard’ appear, referring to this standard, they should beread as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practiceto use a point (.) as the decimal marker.

In this adopted standard, reference appears to certain international Standards for which Indian Standardsalso exist. The corresponding Indian Standards which are to be substituted in their place are listedbelow along with their degree of equivalence for the editions indicated:

Standard

WITH METRIC FINE PITCHTHREAD — PRODUCT GRADES A AND B

(First Revision )

1 Scope

This International Standard specifies the characteristics of hexagon head bolts with metric fine pitch thread withnominal thread diameters d from 8 mm to 64 mm, of product grade A for nominal thread diameters d from 8 mm to24 mm and nominal lengths, f, up to and including 10d or 150 mm, whichever is shorter, and of product grade B fornominal thread diameters d over 24 mm or nominal lengths, 1,over 1W or 150 mm, whichever is shotter.

If, in special cases, specifications other than those listed in this International Standard are required, they should beselected from existing International Standards, for example ISO 724, ISO 888, ISO 898-1, ISO 965-1, ISO 3506-1,ISO 4753 and ISO 4759-1.

Coarse thread bolts according to ISO 4014 should be first choice.
