NATIONAL FOREWORD
This Indian Standard ( Part 1 ) which is identical with ISO 4016: 1988 'Hexagon head bolts -Product grade C' issued by the International Organization for Standardization (ISO) wasadopted by the Bureau of Indian Standards on the recommendation of the Bolts, Nuts andFastener Accessories Sectional Committee ( LM 14 ) and approval of the Light MechanicalEngineering Division Council.
The standard was originally published in 1960 and revised in 1967. Subsequent to thepublication of 1967 edition, many changes had been 2greed upon at international level whichhave been reflected in IS 1367 series of standards covering 'Technical supply conditions forthreaded steel fasteners'. Accordingly, the standard was published in 3 parts covering hexagonhead bolts, hexagon head screws and hexagon nuts.
The second revision of the standard was based on ISO 4016 ': 1979 'Hexagon head bolts ofProduct grade C' issued by ISO. This third revision has been made by the adoption of latestversion of ISO 4016 published in 1988 as Part 1. The remaining parts of the standard, that is,Parts 2 and 3 have also been revised by adoption of corresponding latest version of internationalstandards ( ISOs). The following major changes have been made in this revision:
J
a) The range of sizes has been enlarged to cover sizes from M5 to M64;
b) The range of nominal lengths has been extended up to 500 mm;
c) Non-preferred sizes have been included in separate table in line with ISO 4016;
d) The use of property class 3.6 is also permitted subject to the agreement between themanufacturer and user.
In the .1967 version of this standard, the width across flats for M10 and M12 size fasteners wasspecified as 17 mm and 19 mm respectively. However, in the 1983 version this width acrossflats was brought in line with ISO 4016 : 1979 and specified as 16 mm and 18 mm respectivelyfor M10 and M12 size fasteners. Recognizing the fact that the new width across flat dimensionscould not be implemented immediately, the Explanatory Note to 1983 version of the standardmade a reference to this aspect. However, in the absence of specific coverage in the standard,the new width across flat dimensions could not be implemented. Recognizing the difficulty ofimmediate changeover to new width across flats, the Committee felt that definite time framemay be given to the manufacturers for changeover and accordingly, it has been decided thatwidth across flats as per 1967 version, that is, 17 mm and 19 mm for M 10 and M12 size fastenersshall be permitted till 31 December 1994.
It is also understood that some manufacturers are already equipped and manufacturing as pernew width across flat dimensions and supplies as per new specifications are encouraged.During this period, the manufacture of fasteners as per old version shall be phased out and by1 January 1995, it is expected that the entire fastener industry would have switched over tonew width across flat dimensions and no old width across flats shall be permitted.
In the adopted standard, certain terminology and conventions are not identical with thoseused in Indian Standards; attention is specially drawn to the following:
a) Wherever the words 'International Standard' appear, referring to this standard, theyshould be read as 'Indian Standard'; and
b) Comma ( ,) hes been used as a decimal marker while in Indian Standards the currentpractice is to use point ( . ) as the decimal marker.

o Introduction
This International Standard is part of the complete ISO product standard series on hexagon drive fasteners. The series comprises:
a) hexagon head bolts (ISO 4014, ISO 4015, ISO 4016 and ISO 8765);
b) hexagon head screws (ISO 4017, ISO 4018 and ISO 8676);
c) hexagon nuts (ISO 4032, ISO 4033, ISO 4034, ISO 4035, ISO 4036, ISO 8673, ISO 8674 and ISO 8675);
d) hexagon flanged bolts (ISO 4162 and ISO 8102);
e) hexagon flanged screws; 1)
f) hexagon flanged nuts (ISO 4161, ISO 7043 and ISO 7044);
g) structural bolting (ISO 4775, ISO 7411 to ISO 7414 and ISO 7417).
1 Scope and field of application
This International Standard gives specifications for hexagon head bolts with threads from M5 up to and including M64 of productgrade C.
If, in special cases, specifications other than those listed in this International Standard are required, they should be selected fromexisting International Standards, for example ISO 261, ISO 888, ISO 898-1, ISO 965-2 and ISO 4759-1.
11 These will form the subject of future International Standards.
