0.375" x 1.000" Pre-assembled with a steel backed neoprene washer.
This bolt is used in horizontal and vertical seams for 13 gauge through 13 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.
NOTE: 3/8" x 1-1/2" (S-5060) or 3/8" x 2" (S-9445) Bolts are provided for laminated stiffeners
and splices.
0.375" x 1.500" Pre-assembled with a steel backed neoprene washer.
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 6 gauge 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 stiffener bolts to the splices plates use a
different bolt (one without a sealing washer).
