GPIO Hammer Header Male + Female + Installation Jig

If your soldering isn't quite up to scratch, or you just don't own a soldering iron yet, then these nifty hammer headers might be just the job. They come in male and female flavours, and use crafty little retaining nubbins to grip tightly into the holes on the PCB.

The installation jig kit contains two acrylic base pieces, onto which your Pi Zero or pHAT sits, two steel bolts, two nuts (use these on top of the PCB to hold it tightly to the base of the jig), an acrylic top piece onto which you hammer, and both a male and female header.
