Gauge A shall be placed over the hexagon and shallseat on the flange. G
42、auge B shall be placed on the top of the head normal to the bolt axis. The two gauges shall notbe 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 junction with
43、 the hexagonportion is equal to or greater than specified values. The acceptance criterion is that gauge C shall fit under gauge Awithout contact when the bolt head is seated on a flat plate.Key1 Gauge A2 Gauge B3 Gauge CNOTE Wa, min= etheoreticalWb, max= emin 0,01 mmTa, max= kw, minFigure A.1G50G61
