Knurlies are the first screws out there specially designed for eurorack. Engeneered with love by Befaco to make re-arranging your case a matter of minutes!
Knurlies can be fastened by hand, phillips, slot or allen. And brings a plastic washer already in place to avoid rackrash.
These screws are M3x7mm so they can be used also on those 3mm thick panels as well as regular 2mm ones.
