Chipping away at the bolt faces with a screw driver might help. Use '6 face' impact driver sockets only, the 12 corner sockets will round the bolt corners off. Select an open spanner of the correct size and hammer it mildly from the side onto the bolt head. The spanner will chisel the rust off. Spray with WD40 as this helps release the rust. Try each third of the bolt in turn and wire brush it right down to the base. chisel everything off with a small screw driver and light taps with a hammer. Strike the bolt head full on hard with the ball end of a ball pein hammer. Next see if an impact socket next down a size can be hammered on - corrosion can reduce bolt head dimensions; I've experienced many 15mm bolt reduces to a perfect 14mm fit. Use a breaker bar in the socket and make sure the socket is jammed on deeply as it can be. Try tightening the bolt just a degree before trying to release it. If it still resists remove the socket and apply heat to the bolt head with a concentrated blow torch or acetylene flame - the bolt lengthens through thermal expansion and breaks much of the corrosion on the threads. Furthermore, very hot metal has much lower friction than cold metal. \015\012If you strip the head you will need to use a grinder to create new parallel faces to put a spanner or self gripping wrench on. Many times the heat generated by this grinding process is enough to allow the spanner to remove the modified bolt easily. If still no joy grind a flat top to the bolt, drill it and fit a bolt extractor into the drill hole. Never accept defeat from a seized bolt, persistence pays off. \015\012The worst job I ever did of this type was to try and bleed fluid from rusty brake calipers. The bleed nipple just tore off. I drilled what I could and inserted a bolt extractor and the bolt extractor sheared right off. Hardened steel drills just glanced off the imbedded hardened extractor. I used a Dremel with a chain saw sharpening grinding tool and ground out the extractor's tip. Then, like a dentist doing a filling on tooth, I played the grinding tip around in concentric circles until I could see the rusty outline of the bolt threads of the bleed screw in the caliper. I picked the coil like remnants of the bleed screw from the wall of the caliper and bit by bit cleared the whole thing.\015\012" Failure is not an option" go to it!
