These do sound like Zuckermann tuning pins, with which I have never 
had any trouble at all.

The most important thing is that the holes in the wrestplank must be 
drilled at an angle (so that the wire is at right angles to the 
tuning pin at the point where it leaves it to go towards the nut) if 
one is to avoid the pins pulling out of the holes.  If this is not 
the case, and the pins are vertical, the tension can tend to pull 
them out of the holes.
