East of Dowagiac Michigan | Brock uses a gr 8.2 sealing flange or poly headed bolt. Pretty sure GSI used a hex head cap screw with bonded sealing washer. The old Butler bins used hex headed cap screws with bonded sealing washers. the old Baughman bins used a sealing flange bolt with a flat washer inside under the nut.
Get bolts at least 1" long for roof, floor flashing, and anchor brackets. You can get by with 3/4" for most of the side sheets. |
