Threaded nails for nail gun. Good idea?

[saveasteading]

I didn't know these existed until this week. 

A member of the family came across them and said this would have saved time and material where timbers were out of position.

Instead of destroying, for example, a door frame that is 50mm out,  it could have been unscrewed and adjusted.

 

But they seem to be twice the price. Is it worth it?

Are they commonly used?

Any disadvantages? One must be that screws are screwed, rather than hammered, for a reason....strength.

>>> screws are screwed, rather than hammered

 

I've seen my dad use something he called a 'brummie screwdriver' (i.e. a hammer) to sink screws most of thier length.

 

And he won a few prizes for the wooden sailing dinghies he made.

Yes, because then it is turned in the rest of the way and gets a good fix.

My dad was a carpenter /joiner and tapped screws in a bit in coarsish work where some precision was required, but predrilled for fine work. But also nails  for general stuff where it would never have to come out again.

'Hammering a squint nail in straight' was the ultimate test.

Tapit fasteners used to have a similar threadform, hammered into a plastic wallplug, but removeable by screwdriver.
