I just finished replacing the undersized screws on my slide topper roll ups. One screw had the head broke off. They actually used 3 different screws on the framework above the toppers. There were pan head Phillips, square head Phillips , and several countersunk wood screws also. They almost pulled the head thru the rail. Totally the wrong screws. I added the Oscar rivets to both ends of the mount. Then I changed the steel screws to a #12 x3/4” stainless screws. They fit perfectly. They tightened really good. I did notice one old screw had wet sawdust on the threads when I removed it. Now I’m wondering why. The roof did not have any cracks or tears any where. So I’m wondering if water got past the uncovered screw head. If it did, I should think about putting a dab of silicone on each screw head just as extra insurance.
The repair went well thanks to the advise I got here. So thank you all again.
