    Rounded bolts.

    i got one ONE!!! ONE!!! motherphukking rounded bolt that doesnt wanna move. was rounded even before i touched it. Its getting to me man. If the thread that it screws into wasnt apart of the frame id be grinding obliterating doing all hell to get the cunt off. but no its the other way around. i cant drill it out because if i drill and fuck up or something goes wrong and fucks the thread on the frame then i got a real problem. its for my rearset. its horrible. im thinking of angle grinding a straight groove into it and winding it out with a flathead. but theres got to be some tool out there. some tool in our broad day and age that can simply turn this motherphukkor to the left and ease her out of her position. Aluminum bonds itself together if left for ages. obviously its being left for ages. best to use to top quality loctite so its creates a compound that can be broken not actual metal to metal seizing itself together. hope someone out there can find me a solution. ive being researching for hours. on a positive note ive come to the conclusion on tyga rearsets and new race replica fairings in the suzuki rizla GP scheme. Cool huH! pics in 2 weeks or so when its finished.

    they are called easy outs, drill a hole then using their threaded self tapping 'bits' screw it in the outwards direction and just keep going till the fucker comes out!

    Also I've had some good results by drilling through with the right sized bit until the head pops off, remove your rearset and get some vice grips onto what is left of the bolt. Tap whats left of the bolt with hammer a few times first to dislodge any bonds in the thread.

    It's unlikely to be an ali fastener, though it may well be galled all the same.
    Heat is a possibility if you suspect it is galled and provided the components are able to handle heat it is reasonable to apply some for a start.

    Sometimes though galling leaves no option but to destroy and re-cut the threads or possibly destroy the female thread and use a nut and bolt instead.

    As noted, vice grips are a good first choice if you can get to the bolt. If it's really stuck you may well need vice grip branded grips though. The cheaper ones just don't cut it when push comes to shove.

    An easy out is another possible option (though I prefer them as a last resort as snap an easy out and somehow the easy part is all gone), but I would drill the hole in the bolt with a left hand drill bit as a start as sometimes this in itself will remove the bolt. Centre punch the bolt and drill carefully straight and true.

    If the bike is mobile I have heat, vice grips, easyouts and left hand drill bits etc here if you need a hand.

    Easy outs for the win I reckon.

    The grinding thing wont work because the bolts on an RGV peg hanger are recessed quite a lot. Bust out the drill and go for gold. I prefer to drill the head off completely to get the hanger out of the way, it makes sure there is no pressure on the bolt too.

    Ok if it is recessed then the vice grip idea is out.Would go the eazy out route too,obviously it is fairly well stuck in there because someone has already rounded it off. May be best to accept the kind offer of heat and lefty drill from the nice man.

    First up, is it a 6-point external hed bolt or an allen-key bolt?

    I spend a good part of my working day removing countersunk titanium phillips head screws that are rounded out and bonded into like material anchor nuts. The easiest and quickest way is to drill the head off by starting with a smaller drill (say 1/8" or 3.0mm one) and drilling it beyond the shoulder of the the bolt-head. Then step up to to a drill the size of the shank (probably 1/4" or about 6.5mm). The head will pop off leaving you just the shank in the frame/parent body. You will then have a good idea where the centre of the bolt is.

    Go an buy a QUALITY easy-out. I recommend a 1/8" or 3.1mm 'Snap-on' one - it won't break.

    Drill into the centre of the bolt with the 1/8" drill - don't worry about the expense of a LH drill bit. I have some and although they are awesome, they aren't cheap.

    Penetrant oil and heat, tap in the easy-out, wind it backwards. The good thing with a snap-on easy out is you can tap it while you're turning it.
