you will not find a nicer way to mount euro modules in your rack!
they are the first screws designed for eurorack.
they can be fastened by hand, phillips, slot or allen wrench. And they have a plastic washer already in place to avoid rack rash.
they are available in M2.5X7mm or M3x7mm so they can be used also on 3mm thick panels as well as 2mm ones.
