Appendix A Gauging of hexalobular head A.l General The bolt head is to be gauged using GO and NOT GO gauges in accordance with clauses A.2 to A.4. A.2 Checking of head height Fit head into gauge section A and check that the top of the bolt h
24、ead is either level with the gauge surface or protrudes beyond it (cf. figure A.1.2). If so, the head height is true to gauge.

25、hexalobular part of the head can be fully introduced into gauge section B (cf. figure A.1.3). If so, diameter d, is true to gauge. A.4 Checking head form Fit head into gauge section C and check whether the top of the bolt protrudes beyond the gauge surface. If so, the head is not true to gauge. 1 Ga
