Machine Screw Nuts
Machine screw nuts are the small hex nuts that pair with machine screws — number sizes from #0 through #12 plus small fractional and metric threads. They are used throughout electronics, panels, light assembly, and instrument work. Eugene Fastener & Supply stocks machine screw nuts in steel (zinc), 18-8 stainless, brass, aluminum, and metric.
Choose stainless or brass for corrosion resistance and electrical work, aluminum for light weight, and zinc steel for general use. By the piece or in bulk, same-day shipping before 2pm Pacific.

FAQ
What is a machine screw nut?
A machine screw nut is a small hex nut sized for machine screws, typically in number sizes #0 through #12 plus small fractional and metric threads. They are common in electronics, panels, and light assembly.
What size nut fits a #8 machine screw?
A #8-32 machine screw uses a #8-32 machine screw hex nut. Match the number size and thread (for example #6-32, #8-32, #10-24, #10-32) exactly between screw and nut.
What materials do machine screw nuts come in?
Steel (zinc), 18-8 stainless, brass, aluminum, and metric. Use stainless or brass for corrosion and electrical work and aluminum where weight matters.
Are machine screw nuts the same as regular hex nuts?
They are small hex nuts following machine-screw sizing. Larger fractional sizes are simply called hex nuts; the machine-screw range covers the small number sizes.
