Brass Nuts and Bolts

Brass Nuts and Bolts About

Brass nuts and bolts are durable, corrosion-resistantfasteners made from copper and zinc alloys, prized for their golden, aestheticappearance and non-magnetic properties. Primarily used in marine, electrical,plumbing, and automotive industries, they provide excellent conductivity andare ideal for humid environments. These fasteners are commonly available inhex, machine, and carriage styles. 

Key Characteristics and Technical Details

• Material Composition: Typically, brass fasteners are composed of copper and zinc, which provides a natural, gold-like yellow luster,, sometimes with lead for improved machinability, although lead-free options are available. 
• Corrosion Resistance: They excel in high-moisture environments and resist rust and corrosion, including sea water environments, due to the formation of a protective patina. 
• Electrical and Thermal Conductivity: High conductivity makes them ideal for electrical panels, components, and grounding applications. 
• Non-Magnetic and Non-Sparking: Suitable for electronics, high-speed machinery, and explosive atmospheres where magnetic interference or sparks must be avoided. 
• Machinability and Strength: While less brittle than steel, brass fasteners offer good tensile strength, making them durable for precision engineering. 
• Low Friction: The material has a low coefficient of friction, which is beneficial for moving parts and assembly. 

Common Types and Sizes

• Bolts: Hex head, round head, countersunk (CSK), pan head, socket head, carriage bolts, and custom machine bolts.
• Nuts: Hex nuts, dome nuts, lock nuts, wing nuts, check nuts, and square nuts.
• Threads: Available in various standards, including Metric (ISO), Unified National Coarse (UNC), Fine (UNF), and British Standard Whitworth (BSW).
• Sizes: Common sizes range from 2 mm diameter and upwards, typically customized for engineering applications.
