Search "Hex Plus" on Google. Basically the tool end has a unique shape that grips the inside of the fastener in the corners so you're less likely to damage the fastener getting it out.

But they are expensive. The set in the photo cost me about $70 AU.

EDIT: ... And what Tobra wrote above.

Thanks!

Good idea - will do - thanks Tob!

It won't be able to break the bolt, and probably won't be able to chew the head up, but it'll be able to crack things loose.

Like the idea of an impact wrench - I have a Ryobi cordless too!

We'll see. I hit two of them with the Kroil yesterday and am going back today....

Get up in the morning and spray Kroil on every fastener. Go to beach for the day. Repeat next day. Third day try to take them out with a proper allen wrench. If they don't come right out repeat spray and beach time. Kroil will wick into the threads and they will come out.

They are a bit cheaper here and available on Amazon.

These look good, because Allen style can easily deform the holes which make them harder to use in the future. And Allen head bolts are harder to replace than a regular hex head bolt.

Just have to be careful. They can help break things loose, but they can also more quickly bung things up (strip head, break bolt head off, etc...)

Get a pencil torch and just hit the head so you don't melt the paint on the door. All you are trying to do is break the seal. Then anti seize.

Heat, PB blaster

And a lot of curse words, some even made up

[herr_oberst]

All the above, plus when you first put the tool to the fastener, you might try to tighten it juuuuuusssssst a little, to see if you can release the initial stiction.

You just want to hear that satisfying 'pop'.

The findings of his testing may surprise some here. It surprised me.
