Seized bolt removal

WD 40 is named 40 because when the guy who developed it he tried various formulae and number 40 worked the best.

Such a shame he stopped at 40...

Such a shame he stopped at 40...

A guy with a fag in his gob walked in and asked what the stuff was.
So he didn't make it to 41.

When WD40 was first introduced by Suntester Inc of USA, my father was distribution manager for Western Europe..
Yes it does lubricate.
Yes it does penetrate
But - That it not was it was designed for
And - There are a number of better penetrating oils.
* Plus Gas is one of these.
* I use Unilease - manufactured by Unicorn Chemicals of Blackpool.
I bought three spray cans before Unicorn went out of business.
Best I have ever used.

I never use WD40 as a penetrating 'oil' for releasing rusted nuts and bolts, PlusGas is my go to when I cant find the Freeze type made by LocTite

The best one I've used was called PB Blaster......but its often not easy to find in the UK. Many swear by it on US car forums.

What car is this component from? Don't think I've seen an AF bolt on a Mercedes.

 

[Petrol Pete]

It's not AF , its rotten. The first 'layer' of the bolt/nut is gone . often you will find an (for example) a corroded 8mm bolt will come undone after tapping a 7mm socket on to it.

Atf and acetone make a great penetrating oil. Shake b4 use because it will separate when sitting awhile.

50/50 mix works best.

Regarding the temperature that a chef's blowtorch achieves, I have just ordered a replacement for my failed one from Amazon, and the listing shows that the blue flame (remember bunsen burners in the chemistry/physics labs at school) achieves 1300C!! I originally bought mine for Creme Brulee (when the wife makes her pavlova and leaves 4 egg yolks spare), but mainly use it for lighting candles on things like outdoor citronella, table centre food warmers etc, which it did really well!

Those heated coil guns work well for undoing seized nuts and bolts but obviously only if you have good access. WD now to a range of specialist sprays apart from 40.

A lit match will burn at that temperature. There's more to heat than temperature.

 

[ALFAitalia]

A lit match actually burns at a temperature of around 600–800°C.....but as you say its the energy used to keep adding heat at a high rate that matters.

Thats why Oxyacetylene works so well, I used to have a mini set that I acquired through a bankruptcy but the hoses rotted out and I couldnt get it refilled because the bottles were not registered to me (or something like that, can't really remember) . You can buy tiny sets with disposable bottles but not something I need anymore and probably a bit much for the average DIY guy.
