Foreword
In order to keep abreast of progress in the industries concerned, British
Standards are subject to periodical review. Suggestions for improvements will be
recorded and in due course brought to the notice of the committees charged with
the revision of the standards to which they refer.
A complete list of British Standards, numbering over 9,000, fully indexed and
with a note of the contents of each, will be found in the BSI Catalogue which may
be purchased from BSI Sales Department. The Catalogue may be consulted in
many public libraries and similar institutions.
This standard makes reference to the following British Standards:
BS 449, The use of structural steel in building — Part 2: Metric units.
BS 4395, High strength friction grip bolts and associated nuts and washers for
structural engineering. Metric series — Part 1: General grade.
BS....., Podger spanners. Metric series1)
.
BS 3294-12)
 gives rules for the use in structural steelwork of high strength
friction grip bolts of the general grade specified in BS 3139-13)
. Both those
standards are in imperial units.
The present standard is now issued, in metric terms, to cover the use of general
grade bolts as specified in BS 4395-14)
. The technical content is substantially that
of BS 3294-12)
.
The tightening methods specified in the standard both aim at a shank tension of
at least the proof load. Tests and experience show that the excess over proof load
obtained in practice is not detrimental. The design factors also are based on
extensive experimental work. Variations in them are permissible, under the
engineer’s authority, where the structure, the materials or other considerations
demand them.
The use of higher grade bolts will be covered by Part 2 (Parallel shank bolts) and
Part 3 (Waisted shank bolts), which are in course of preparation.
The metric values are given in SI units, details of which are to be found in
BS 37635)
 and PD 56866)
.
A British Standard does not purport to include all the necessary provisions of a
contract. Users of British Standards are responsible for their correct application.
Compliance with a British Standard does not of itself confer immunity
from legal obligations.

1 General
1.1 Scope
This Part of this British Standard specifies requirements for the use of high strength friction grip bolts of
the general grade, as specified in BS 4395-17)
, in friction grip connections in structural steelwork which
complies with the requirements of BS 449-28)
. The standard also specifies requirements for the use of high
strength bolts as ordinary bolts (see 1.3).
1.2 Definitions
For the purposes of this Part of this British Standard the following definitions apply:
1.2.1
high strength friction grip bolts
bolts of high tensile steel, used in conjunction with high strength nuts and hardened steel washers, which
are tightened to a specified minimum shank tension so that transverse or axial loads or both can be
transferred between the connected parts otherwise than by shear in, or bearing on, the bolts
