Harwin still make those. They're called "track pins".

http://uk.farnell.com/harwin/t1559f46/track-pin-0-84mm-pk500/dp/1143874 (500x)
http://uk.farnell.com/harwin/t1559f46k/track-pin-0-84mm-pk1000/dp/1143879 (1000x)

£8.04 for 500, £13.23 for 1000. Harwin part numbers T1559-F46 and T1559-F46K
respectively.

Or if you want the 1mm diameter ones:

http://uk.farnell.com/harwin/t1563f46k/track-pin-1mm-pk1000/dp/1143880 (1000x)

£6.44 for 500, or £13.66 for 1000. Harwin part numbers T1563-F46 and
T1563-F46K respectively.

I didn't really rate them -- the large head on the pin usually meant that even
if you followed the design guidelines ∗exactly∗, the pin would short to a
nearby pad.

And wire + solder is cheaper :)
