A screw is used as a fastener together with a nut or a standoff.
We have here a pack-of-4 cross cylinder cap nylon screws. The thread size is M2, it fits other M2 screws/standoffs. The thread length is 4mm
Nylon fasteners have several advantages compared to copper, brass or other metal fasteners. They are lighter, non-conductive and non-corrosive.
