MCIGICM 10pcs Male Header Pin, 40 Pin Header Strip (2.54 mm) for Arduino Connector

Excellent quality and inexpensive. Just what the doctor ordered.

The pins are good. I didnt consider pin construction when I bought these. These square pins do not fit the round pin female headers that I bought. It is not worth the time and expense to return these, I will most likely buy square female headers for future projects. I have already bought round pin male headers to mate with the round pin female headers. Make sure you specify round or square pin header when you search for pins.

Very good.
