The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. ISO 14278 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 4, Aerospace fastener systems.

Patent rights are held by the Phillips Screw Company worldwide. ISO takes no position concerning the evidence, validity and scope of this patent right. The holder of this patent right has assured the ISO that he is willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with the ISO. Information may be obtained from: Phillips Screw Company 508 Edgewater Drive Wakefield, MA 01880 USA Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights other than those identified above. ISO shall not be held responsible for identifying any or all such patent rights.

The internal offset cruciform drives, ribbed drives and unribbed, respectively are defined in ISO 14275 and ISO 14276. 2 Configuration and dimensions See Figures 1, 2 and 3 and Tables 1 and 2. Dimensions and tolerances are expressed in millimetres. The presentation of surface-profile, perpendicularity, location and run-out tolerances conforms to ISO 1101. 3 Designation The GO and NOT GO gauge designation shall be as follows: The component part designation shall be as follows: The drive penetration gauge assembly (see Figure 3) shall be identified by the gauge body designation.
