Is JB Weld overrated as hell or am I using it wrong?

I'm trying to re-attach the head of a hollow bolt to the threaded bit, which has sheared off. Having heard countless stories from more mechanically-inclined friends about patching oil pan leaks with this stuff, fixing cracked engine blocks, etc., I figured this had a good chance of working. (The bolt plugs the drain in the oil pan of my 49.5cc scooter.) Two attempts now (with the full 15 hours curing time each) have failed miserably, with the head popping off merely from my attempt to screw it back in place (there is a spring which fits into the hollow section of the bolt which applies pressure as the bolt is tightened). The first time I didn't mix the two compounds sufficiently, only applying one compound to one piece and the other to the other piece and then sticking them together. The second time I mixed thoroughly before applying and had the same result. WTF?
