A machine nut is used with machine screws to connect materials together mechanically. This type of nut is used with smaller machine screw sizes under 1/4". Hex Machine nuts are used for many fastening applications. Machine screw nuts are often used with hex cap screws, socket screws, and bolts.
Small Diameter Machine Screw Nuts
A machine screw small pattern nut (micro) is used with machine screws to connect materials together in small tight areas mechanically. Small Pattern Machine Screw Nuts have a smaller outside diameter than standard Machine Screw Nuts. For example, a #0-80 Machine Screw Nut has 5/32 (0.15625) inch flats, whereas a #0-80 Small Pattern Machine Screw Nut has 1/8 (0.125) inch flats.
Brass is an alloy made of copper and zinc. The color of brass can vary from dark to light based on the zinc content; more zinc content produces lighter brass. Brass is prized for its appearance and is often used decoratively. However, it is quite soft, so it is not suitable for all applications. Brass conducts electricity and is also a good conductor of heat. Brass threaded rod is made of solid brass instead of brass plated steel.
Do machine screws need nuts?
Machine screws typically only need nuts if the hole they are being fastened into isn't tapped or the screw goes through completely, leaving the end sticking out on the other side. Even in the latter scenario, a nut is not always needed but is usually recommended. Ultimately, it depends on the application. We recommend using nuts where applicable since they can help secure your application better than the screw alone.
What is a screw nut?
A screw nut is a type of mating fastener to bolts. It has a threaded hole, which fastens multiple parts together when used with a bolt or machine screw. These two parts are kept together through friction and compression.
What is a machine screw nut?
Machine screw nuts are finish nuts designed for use with smaller (under 1/4 inch) diameter bolts. They are most often used with machine screws.
How strong is brass?
Brass is stronger and harder than copper, but not as strong or hard as steel. It has great formability and is resistant to saltwater corrosion.
What is the difference between brass and bronze?
Brass is highly malleable, has a dull gold appearance, good saltwater corrosion resistance, and isn't as hard as steel. It's used for decorative purposes and in marine applications. In contrast, bronze is hard but brittle, has excellent corrosion resistance against salt water, tends to be a reddish-brown color, and is used in marine applications on boats and electrical connectors.
