Precision extension pin strips..

[NicMac]

For some op-amp adapter PCBs I need extension pins like the one shown in the attached picture. I have now spend more than an hour trying to locate these silly thingies in the Mouser catalog without any luck😡
Would somebody possibly know a part number for such pin strips (preferably Mouser)?

I would call that a pin "header".
