through which 0.375-inch 16NC2 or 16UNC2B holes have been tapped, shall be screwed

tightly onto shanks, the upper ends of which have been threaded for a distance of

approximately 0.4375 inch with 0.375-inch 16NC3 or 16UNC2A threads. The part of the

shanks which protrudes through the head shall then be heated and peened over so that the

peened portion of the shank overlaps the bolt head such that it is impossible to unscrew the

head from the shank (see figure 3).
