I'm looking for a .1" pitch female-female or female-male header with common pins, i.e. all the pins are connected. I'm sure it exists, I'm just having trouble coming up with the right keywords to find it on google.
I want to use it as a cheap way to expand the ground and 5V terminals on an arduino without needing a whole shield.

For a cheap solution, I would cut one lead off of a resistor, then lay it across all of the pins in your female-male header. Then solder the lead to each pin. In the following image, the green line represents the lead, and the red ellipses are the soldering points.
