Darn frozen bolts...help

I love everything about working on these old bikes with one exception...frozen bloody bolts!!

Any thoughts on how to get these rounded frozen bolts out? Can't get heat to them as the plastics will be destroyed. Have tried soaking in Kroil and doesn't seem to make any difference (I genuinely believe all of these release agents are made of snake oil!), tried my Irwin bolt removers and can't get enough purchase on them..

These are the last bolts that have to come off and the 'painful' work will be over.. so frustrating..



Help - so near and yet so far Smile

Use an impact driver. Put your 8mm socket on it and strike it both clockwise and counterclockwise to break it loose

Edit: didnt see they were rounded.

May have to cut or drill the heads off. That will allow you to at least get the plastic off and use heat to get the left over stud out.

In the future use anti sieze on every bolt that goes into alloy material.

Hit them with some Freon they will shrink and Possibly come out.

Thanks for the posts all.

Will give the freeze treatment a go first and then dig out the drill/Dremel if it comes to that!

When the bike is assembled I'll defo be using some anti-seize compound. Someone in the future might be glad I did!

Drill the head of the bolt off.

Plastic is off then, so you can then address the remnants of the bolt, there being many ways of doing so. Goodness knows what has caused such seizing on those sort of mount bolts. Something like red loctite used, a gorilla swinging off the bolts etc etc.

I have seen plenty of non genuine, replacement 8mm head, flanged bolts round off the heads, leading me to just stump up for Genuine Honda bolts, no matter the price.

They seize because steel bolts in aluminum corrode.

Any time you put a bolt into aluminum, it has to get something on it. Grease, anti seize, or thread lock.

Thanks..

I've only just bought the bike and it was sitting around for a long time before I bought it hence the issues.

Build is here for anyone interested Smile

Yep, drill the heads off to get plastic out of the way, then have a decent welder lay a slightly larger nut over the stud, and weld the two together. The bolt will expand, then contract when it cools. Put a wrench on the nut, and remove. Usually they come right out, sometimes a little penetrating oil on it while still warm helps, along with some careful back and forth working the bolt to free it. If done by anyone with average intelligence you won’t damage anything.

I'm pleased to say that freeze spray and needle nosed pliers solved the issue. Pretty impressed with the freeze spray actually. Wasn't convinced but thought I'd give it a go and it worked great. Another tool in the fight against stuck fixings!

TAke a 12 point socket that’s 1MM smaller than the head and hammer it on. Works every time 80 percent of the time

I know it's solved, but another method could be to take a dremel with a cut off wheel and cut a single slot in the head, so it looks like you could use a flat head screw driver. Then use an impact with a flat head on it.
