Stuck shutter hinge screw
One of DD's shutter hinges broke in a line right where 2 of the 3 screws go through it. She has been able to purchase a replacement hinge that will allow her to use the same screw holes in the brick. She has been able to remove the top and bottom screws AND the brick-side leaf of the hinge. However, she cannot remove the middle screw from its hole.
Because the hinge leaf broke across the screw hole, she was able to remove the hinge leaf. She has tried everything to remove the stuck screw. Just to help you envision the situation, on the brick side of the hinge, there is no hinge leaf and 2 of the 3 screws are gone. The middle screw is stuck. It will rotate, but it won't come out or go farther in.
To unscrew the screw, she has tried a hammer drill, a regular drill, a manual screwdriver, and pliers (the head is sticking out enough to grasp with pliers). As I said, the screw turns but doesn't move in or out.
Can she take a hack saw, cut the stuck screw off even with the brick, and just replace the shutter hinge with screw in the upper and lower holes? Is there a better "DIY with limited tools and skills" solution?
