Brass fasteners are used for their physical and aesthetic properties. Brass is utilized due to its high thermal conductivity and corrosion resistant properties, it is suitable for use in hot and cold environments, and resistant to water corrosion, making it a staple of industries such as heating and plumbing. Brass fasteners are largely non-magnetic (like any fastener, slight magnetic properties can develop during the manufacturing process) and resistant to tarnishing.
Brass fasteners are suited for some marine environments, including brackish water and slow current sea water; brass in this environment develops a protective green coating. Brass fasteners are also commonly used with wood applications, as the golden coloring blends well with the tan wood. Brass is a softer metal and must be used with care, always drilling pilot holes and using driver bits that fit the head of the screw precisely to prevent stripping. Brass Bolts also require a pilot hole be driven before installtion.
