I need to determine what screws should be used to connect a 5/16” plate to light gauge rafters and roof trusses. See the attached sketch. The wind uplift is around 80 pounds/foot. The 5/16” bent plate will support a gutter, which will weigh 16 pounds/foot if full of water. The building is in Florida.
What screws would you use in this application? If installed from above, the screws will go through the 5/16” plate first and then the light gauge. Hilti has a self tapping screw (S-MD 12x24/1-1/4 HWH #5) that will provide plenty of capacity. Have you specified this screw for this application? Did you get good results? Could the screws be installed from below?
Thanks
