 8.3.1.1
Chain Stud Anode. This cathodic protection system consists of an anode
and a bolt assembled to the stud link as shown in Figure 8-4. For each size
chain, a particularize bolt and anode are required (see Table 8-l). Each
anode is stamped with its type. During anode installation on each chain
link, the recommended torque to be applied to the bolt is 25-35 foot-
pounds. If, when attempting to replace a depleted anode, a bolt head is
found to be missing, the center of the remaining bolt should be tapped
with a counter-clockwise l/8-inch thread so that it can be removed using
a counter-clockwise threaded bolt and a hand- or electric-powered
wrench.
