Decent stackable header

[alank2]

Well, my 2x20 stackable female header arrived from eBay and it is junk.  The pins are not 0.025 square pins and bend very easily....

Does anyone know/recommend a place for stackable header that is like what I see on STM32 dev boards (it is too sharp, but it is strong)?

Samtec make just about any form of header you could ask for.  They're pretty generous with samples if you only need a couple, I'm not sure about moderate quantities.

This one works well for me:

For other sources search for "PC104 stackable headers" on ebay

How rigid/strong are the pins?  I ordered some like this:

The pins are all bendy just from handling them...

The pins are strong.  They are almost square.  My measurements indicate about 0.025" x 0.022".

Excellent; thank you; I'll give those a try!
