1、BRITISH STANDARD BS EN 14219:2003 Incorporating corrigendum no. 1 Hexagon bolts with flange with metric fine pitch thread Small series The European Standard EN 14219:2003 has the status of a British Standard ICS 21.060.10 BS EN 14219:2003 This British Standard was published under the authority of th
2、e Standards Policy and Strategy Committee on 29 August 2003 BSI 2007 ISBN 0 580 42544 4 National foreword This British Standard was published by BSI. It is the UK implementation of EN 14219:2003, incorporating corrigendum February 2007. The UK participation in its preparation was entrusted to Techni
3、cal Committee FME/9, Bolts, nuts and accessories. A list of organizations represented on FME/9 can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a Br
4、itish Standard cannot confer immunity from legal obligations. WARNING The United Kingdom, as a member of CEN, is obliged to publish EN 14219:2003 as a British Standard. However, attention is drawn to the fact that during the development of the European Standard the United Kingdom consistently voted
5、against its approval as a European Standard. The UK believes that the corresponding International Standard, ISO 15072:1999, should have been implemented, without modification, as a European Standard. As far as the UK is concerned, it is dangerous and unacceptable to have a European Standard that dif
6、fers from the corresponding International Standard by the across flats dimension for one size of fastener, all other requirements being identical between the two standards concerned. As part of BSIs duty of care, we draw the attention of users of this standard to our concerns that M12 bolts conformi
7、ng to EN 14219 differ from similar fasteners conforming to ISO 15072 in the across flats dimension only. This is 16 mm in EN 14219 and 15 mm in ISO 15072. BSI will assume no liability whatsoever for the failure on the part of any user of this standard not to consider this aspect. Precautions are urg
8、ed to ensure that commingling of those M12 bolts which conform to EN 14219 and those M12 bolts which conform to ISO 15072 is avoided. Amendments issued since publication Amd.

45、ethod for gauging of hexagon (see Figure A.1 and Table A.1) The head shall be gauged using two ring gauges, A and B, to demonstrate the coincidental acceptability of hexagon height, wrenching height, corner fill and width across corners. Gauge A shall be placed over the hexagon and shall seat on the
46、 flange. Gauge B shall be placed on the top of the head normal to the bolt axis. The two gauges shall not be in contact. A.2 Recommended method for gauging of flange thickness (see Figure A.1 and Table A.1) Gauge C is a flat feeler or ring gauge. It is used to prove that the flange thickness at the
47、junction with the hexagon portion is equal to or greater than specified values. The acceptance criterion is that gauge C shall fit under gauge A without contact when the bolt head is seated on a flat plate.
