Be careful with those stuck threads. Lots of reports about stripped bolts and masts needing to be cut down on the forums ( including me). Lots of penetrating oil, heat and patience required.
Hmm. Yeah, it is really a pain. Any additional/more detailed advice or technique would be welcome.
Drilling is one option but to be honest it's your last resort. Once you drill your are committed to that course of action and it's too late to turn back.
I found good info on other forums and YouTube but basically soak the area in penetrating oil like wd40 for 24 hours. Boiling Also sounds good. Heat can help as the metals will expand at differnt rates - you can buy cheap butane gas camping torches from Bunnings. So use heat and your penetrating oil together. Also tapping the head of the bolt with a punch can work to break the salt / corrosion bond (hit vertically with a punch down in the direction of the shaft, not across ). One option is the weld a nut on top of the bolt and undo it with a spanner. Be careful which size Allen key you use because metric and imperial are very similar in some sizes. Try and avoid stripping the head if it's not too late.
if it's too late then try and drill the head off only, and if you can gets the wings or fuse off leaving the remnants of the bolt sitting proud you can try and use vice grips on the remaining stub to get it out. Worst case is to cut the mast and retap.
