This bolt is used in horizontal and vertical seams for 13 gauge through 12 gauge laminate sidewall to
attach the sheets of 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.

It is used to connect the stiffener to the sidewall at locations where a splice plate is used to
connect the stiffener and to connect laminated stiffeners to the sidewall sheets. It is also used to
bolt stiffeners to 9 gauge and thicker sidewall. This bolt is also used to bolt horizontal and vertical
seams together on 11 gauge laminated and thicker and some overlap seams. It is only used to attach
the stiffener and the splice plate to the sidewall. The flanges where the stiffeners bolts to the splices
plates use a different bolt (one without a rubber washer).
