First I want to know why the screw strips like that. I drill pilot holes into a thin piece of metal. I am trying to fit bolts in this structure. The first side worked perfectly and is held together with a nut. The second one didn't work because I drilled the pilot hole on an angle. I am hoping to solve the problem with a bigger bolt. How can I create threads? Do I need to tap and die this thing piece of metal.
