Thread: Please help! Stuck bolt.

Pics showing the lay out would be useful

Heat?

If the bolts protrude then direct heat with a small flame for around 30s - even a cigarette lighter might work.

If they are in a recess then a soldering iron for a few minutes.

Did you try a breaker bar or a manual ratchet as well or just the Ryobi Impact Driver?

If you just used the impact driver, I'd suggest you try using a breaker bar and giving it a sharp rap with a mallet or block of wood.

There are impact drivers, and there are impact drivers.

You can't beat the old hand held punch type drivers.

eg. Impact Driver - Robson's Tool King Store

Run rings around those woosey cordless toys.

And then if it is a decent impact driver the bit will tear the soft (most likely chinese) bolt apart.

Its an old hafco saw. So Taiwanese bolt :P

I will give my seriously impact driver a flog and see if it budges

ok give it as much of a soak in some penetrating oil as you can. give the bolt a very good whack with a hammer and punch and try to tighten it with the impact driver then try loosing.
if this doesn't work try heating or cooling there is a lock tight spay for loosing seized bolts.
wuth rost off is a good penetating spay.

If it is that tight, go for the heat before you try and turn it hard enough to break the bolt.

A picture of the suituation would help

Understandable, i will get some tomorrow when I'm in the workshop

Can do.

Where people go wrong is using a rattle gun for this sort of job.

A rattle gun is NOT an impact driver and will probably skip and tear up the head (if it's slotted) and can tear off the head if it's a bolt.

The old hand held impact punches are the most controllable (regarding amount of force applied).

+1 on applying a bit of heat - small butane jewellers type flame would work wonders on a steel to cast iron problem.

Steel to alloy is a bit different in that the alloy actually grows into/physically bonds to the steel over time. That's why you have to use an impact driver when disassembling most types of motorcycle engines.

Apply heat as per Robs suggestion. This will compress all the rust etc in the threads. Then chill the bolt with a freeze spray can. Available from electronics suppliers like Jaycar. This will shrink the bolt and hopefully create some clearance. Get penetrant on first so hopefully the shrinkage will draw it in to the threads.

For penetrant, you can't go past atf(auto transmission fluid) and acetone. Mix a bit up and brush it on. The acetone wicks the atf into any miniscule gaps and then dries out leaving behind the atf.

If there's one thing farmers can't resist, it's some new form of MAGIC rust penetrator snake oil that the sales rep flashes out of the sample case

Given the amount of rusted up gear on farms it's no wonder.

My bro in law is an absolute sucker for this stuff.

Every time I see him he shows me some new rust debonder/eater/dissolver/destroyer/incapacitator ete. etc he's just bought - and it's never cheap.

Always have a chuckle when I hear what it can do. Some of it actually works.

Are you having a go at me? That last penetrant I bought actually worked, as a fire lighter. LOL.

Actually I have only had one salesperson come here in the 13 years we have been here, except for the occassional visit from a stock agent. I have also only had two visits from religious organisations in that time. There are some benefits to living in the bush.

I agree with the ATF and acetone. This was claimed to be the best penetrant in a non lab test done by a car magazine. Don't ask me details, I was just researching for the best penetrant on the net.
