My tiny company is the manufacturer of the push nut install tools sold by McMaster and MSC.

The tools are pretty expensive when compared to a mass produced tool like a screw driver. but consider that we make all of a few hundred a year, and consider how much it would cost with internal overhead to actually make a nice tool with hardened and magnetized shaft and a comfortable handle for installing these ornery fasteners and you have a good deal I think! (several hundred dollars at a minimum.)
