16、rldwide federation of national standards bodies (ISO member bodies). 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 o
17、n 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.The procedures used to develop this
18、document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Dire
19、ctives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the devel

24、g method.The curvature of the contour of the hexalobular internal driving feature is defined by the gauges specified in Tables 3, 4, and 5. Additional information which can be used when drawing the contour is given in Annex A.The intent of this International Standard is to provide the details necess
25、ary for inspection of the hexalobular driving feature. It is not suitable for, nor intended to be used as, a manufacturing standard.2 Basic dimensionsSee Figure 1 and Table 1.Counterbore: c 0,13 mm up to socket no. 15c 0,25 mm over socket no. 15Penetration depth, t: see relevant product standard.aSe

In the case of oval or
31、round top heads, measurements are taken from the actual intersection of the top surface of the head and the hexalobular internal driving feature counterbore.When using a dial penetration gauge, this should be adjusted to zero while the gauge is pressed against a flat surface, thereby compressing the
32、 plunger to make it flush with the gauge reference surface (see Figure 2).Figure 2 Dial gauge (zero position)3.2 GO gaugeThe GO gauge dimensions (see Figure 3) shall be within the limits specified in Table 3.
