in. wall thickness. All three have the same meaning per Table 1-1, in the 6-in. size. Stud Bolts ANSI Flange Bolting In ANSI piping, stud bolts are stamped with identifying numbers on the ends of bolts and the face of the nuts. A common mark for bolts is B7, and Grade 2H on the nuts. The bolts are often plated with various coatings, some of which are listed below: Plating Marking Cadmium B7 Zinc L7 Chromium B16 Tin B8 Silver B8M Stud bolts are shipped from vendors as so many bolts/ nuts per pound. If the purchase order states 100 stud bolts with two heavy hex nuts each, then you may re- ceive 99 or 102 bolts with nuts. To save time, and avoid counting each bolt, verify the total weight as being cor- rect, verify about 25% of the markings per the specifica- tion, then store the bolts in the shipping container rather than using valuable warehouse shelving space. 19
Do not grease, spray, or clean bolts without specific in- structions from your supervisor. Do not store new bolts with used bolts. Machine Bolts The machine bolt is commonly used for slip-on and threaded flanges. Only one heavy hex nut is required for a machine bolt. Both the bolt and the nut are identified the same way as for stud bolts. Measuring Stud Bolts A fast way to measure a stud bolt diameter is by measuring the thickness of the heavy hex nut; for example, a 1/2-in. diameter bolt has a heavy hex nut that is 1/2-in. thick. Measure the length of stud bolts to the nearest 1/4-in. from thread to thread, less the point heights as shown in Figure 1-13.
