What Are Custom-Sized Brass Spacers?

A spacer is a hardware component that creates a gap between two objects, improving assembly and alignment. When it comes to brass spacers, these are typically used for their excellent machinability, corrosion resistance, and electrical conductivity. Custom-sized brass spacers are specially designed to meet unique project requirements that standard sizes cannot satisfy. These can range in diameter, thickness, and length to meet specific dimensions.
