They are threaded steel or stainless-steel rods, typically around 2 mm diameter, force-screwed through undersized holes drilled across the split, sometimes at slight angles.

The extra length is broken off just below the surface of the entry holes.

Then the entry holes (and exit holes if there are any) are filled with a back glue/filler, often made from blackened epoxy, or black timber dust and superglue, and finished such that there is little or no evidence of the invasive operation.

Of course the rods crosses the crack quite deep within the timber, quite close to the bore, so it is arguable as to just how much the pins stabilise the splits, which are actually typically at their worst close to the OUTER surface.

Modern glues arguably do a better job of stabilising splits than pins can. Of course, as with all operations, the success or otherwise is in the detail of how the work is done, no matter which techniques are used.
