These are perfect for my electronics projects to act as terminals for my benchtop power supply to attach to. Their resistance is pretty low (1-5 Ohms), so I don't anticipate they'll be an issue with charging my batteries

This is nice assortment of M4 thumbscrews in a compartmentalized box for easy storage. The threads are nicely cut and the knurling is decent if not real sharp. Thread diameters are just a little undersized on some lengths vs. ISO minimums but all work fine in M4 threaded bosses and nuts. There is no shoulder under the heads so they will be flush when securing flat panels which may be inconvenient. For most other uses particularly when a quick adjustment or securing and removing parts without tools, these should do just fine. I have already used them to secure a sliding rod collar on a 3D printer.These would be a worthy addition to anyone's fastener hoard.
