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.
Silicon bronze fasteners are made of copper, silicon, and various other alloys such as zinc, tin, iron, and manganese. The color of silicon bronze may vary based on the amount of copper in the fastener. Silicon Bronze is superior in corrosion resistance to 316 stainless steel, though it is more expensive than most fasteners. It's used in marine environments, corrosive environments, and high heat environments. Silicon bronze is similar in color to copper and is sometimes used in finish applications for the color.
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.
What is silicon bronze used for?
Silicon bronze is used primarily in marine applications for its high corrosion resistance, non-magnetic properties, rich appearance, and ability to resist the corrosive action of water.
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.
