What do the surfaces of the hammer and nail head look like at this level?

STM Image of Iron

In your post title, you ask for details at the subatomic level, which I don't think anybody can provide you with.

So I have cheated a bit, and displayed a Scanning Tunnelling Microscope Image at the atomic level, which may be on the scale of the best image we can currently obtain.

What I find interesting about this image, is that is corresponds exactly with what we would expect to see classicaly, all nicely lined up and ordered neatly.

I would doubt that the subatomic level is even possibe to visualise, in other words, an electron is supposed to be an point shaped particle, that takes a 720 degree rotation to get back to its starting point, I have no idea how to visualize that.

The nearest image I can provide you with, where quantum effects start to come into play, is the one below.

From Wave Like Motions

The concept of wave-like motion for electrons has been very difficult to imagine or visualize. What does it mean for a particle to move like a wave? But we can visualize it. Very recently, scanning tunneling microscopy (STM) has been used to take images that clearly reveal this wave-like character. The STM mechanism can be used to literally pick up and place metal atoms in specific arrangements on metal surfaces. For example, iron atoms have been arranged to form a closed circle on a copper surface. An image of the resultant structure then taken using the STM shows not only the ring of iron atoms but also conspicuous waves inside the ring, which result from the motion of electrons moving within the ring and reflecting off of the walls formed by the iron atoms. Two of the original images taken at IBM of these so-called “quantum corrals” are shown below.

This Wikipedia STM article explains the details of the STM, and how it uses the the quantum tunnelling effect to display an image, not of the atoms themselves, but of the electric charge surrounding them.

Any corrections / clarifications to the above statement will be welcomed.

Are they well defined boundaries, or are they "clouds of subatomic particles" that interact or are exchanged at a certain proximity ?

On a subatomic scale, they are not well defined boundaries, and I am pretty certain we cannot visually image an electron, all we can do as in the above images, is produce an image based on the indirect effects of their electric charge on our instruments.

As far as proximity relates to interactions, you should read this Overlapping Orbitals post and the comment by CuriousOne below it, on the factors that influence whether an interaction will occur or not.

How exactly is the momentum transferred from the hammer to the nail?

By exactly the same method as we are able to walk across on a floor, that is the electrical repulsion of similar negative charges, as the electrons repel (or attract) each other by momentum exchange mediated by photons.

QED, our theory of how particles and forces interact, is well summarised by Wikipedia.
