This bolt is used in horizontal and vertical seams for
13 gauge through 12 gauge laminate sidewall to attach the
sheets to each other. It is also used to attach the stiffener to
the sidewall sheet for up to 10 gauge sidewall. It is not used
to splice the stiffeners together on the flanges where they
connect to each other or the splice plates. These are also
used to attach the hopper panels to the hopper support
beam for the NCHT’s with diameters of 30' and less.
