I use the pins of old computer cpu sockets for this.
they have a hell lot of pins and are of no good use anyway (if you don't
need a cpu
on your board). the ones without the lever from 386/486 cpus are fine.
they have the round turned socket pins embed in a rather hard brittle
plastic.
(can be easily broken free with side cutting pliers)

such old mainboards are easy to get here, and as said one has quite a few
pins...
and they cost no 10 cents.......

are designed for round pins, with a leaf spring inside i think, perfect
for resistors
but do work too with flat dil pins... (but dil sockets are cheap)...


BUT they do not fit into the hole (to be flat with the pcb), unless you
make it 1,5mm or so.
(they have a thin wire on the end like a turned pin dil socket).
