connector - Is there a device which replaces soldered pin headers?

I have to flash several devices and up to now I was soldering pin headers to attach the device to my PC.

I will soon have 20 or so to flash and would like to avoid messing up with the soldering part (soldering is great but I just need the header pins to be available for 30 seconds and never reuse them afterwards).

Is there a device I could use to avoid soldering them? I saw some hacks where people were doing all kind of gymnastics with bent pins and it worked or not -- I was rather thinking of some kind of a prong to reliably touch the contacts during the flashing.

Answer

Pogo pins are one method of making a test or programming jigs.

The alternative is another connector like press fit headers. These use friction and sometimes displacement to cut into the pcb. Functionally identical to soldering headers, but without the soldering.
