Do your '0.1" (2.54mm) Crimp Connector Housing: 2x20-Pins' fit correctly onto the raspi gpio pins?

Hi there,
I am using pololu jumpers on my raspi 4b gpio pins and am having problems with them as they keep slipping off the gpio header pins and I end up with raspberry pi boards burning out / no longer working.
The best solution I can find is to remove pololu jumper wires from their end connectors and plugging these into the ‘0.1" (2.54mm) Crimp Connector Housing: 2x20-Pins’ product.
Could you please confirm that these connectors will fit firmly onto the raspberry pi 4b gpio male header pins?

Hi Nick,

I believe I spoke to you on the online chat about this one, My advice was to use Crimp Pins
They’ll be a firm fit for sure, but crimping your own wires with crimp pins is probably a more sensible option than using single ones.

All the best with your project!
