Monte, the thing is with these crush washers is that they start out with a slight dish. The through hole is parrallel, and when it is "crushed", and the curvature is flattened out, the hole becomes smaller on the convex end. This usually smashes the I.D. against the threads, or just below the relief for the threads. You might try to unscrew it. Usually when I get them off, I open the hole up with dremel to prevent the hole from compressing against the threads and limiting the amount of crush.
