Nylon Insert Lock Nuts - Machine Screw Sizes

These are nylon insert lock nuts in machine screw sizes, #2-56 through #12-24. The nylon ring grips the screw threads, so small screws stay tight in electronics, appliances, enclosures and light equipment without lock washers or thread locker. They are zinc plated steel (NM style) for general purpose use.
