I have a problem holding thin aluminum, about .080", together for a period of 3 - 4 months in an outdoor environment. I have tried drilling and taping with # 8, 10, 12, fine & course thread machine bolts, which last a few cycles then strip out. The force needed is about 3 - 5 lb compression. I only have limited access to one side of the joint. I'm now thinking of a finer thread screw such as drywall screws which are designed for metal studs. Any thoughts or suggestions??
