: I have an aluminum steering gear housing with a bolt broken off in it. The bolt is about a 3/8" x 1 1/2" bolt. I've already drilled the center of the bolt out with about 7/64" drill bit the entire length of the bolt. Only one end of the bolt is visible. I tried to use an easy out but it wasn't budging and I didn't want to break the easy out off in the bolt. : Can I heat aluminum? Can I try to weld a new bolt head to the bolt? Should I just drill it out completely and use a heli-coil? : Please comment. The easy out for a 7/64 drill is pretty small and I'd worry about breaking it. If the current hole is in the center, drill it out for a larger size easy out. This will let you work it harder without worrying so much about the easy out breaking. If this doesn't work just drill it progressively larger. It may loosen when you get closer to the edge, or if it doesn't, you can just drill it out. I suggest that you don't use a heli-coil though, they are junk, especially in aluminum where they can partially pull out. Use a key-insert, it's a solid steel insert, threaded on the inside and out, it has little keys that you hammer in which keeps it from unscrewing. They are available from most industrial suppliers.
