Precision Brass Spacers for Reliable Component Spacing & Electrical Conductivity


1.Product Overview

Our custom CNC turned brass spacer is engineered to solve industrial component spacing and electrical connection challenges. Produced via advanced CNC lathe processes from high-grade brass alloys, this non-standard component features a hollow cylindrical body with through-hole or threaded bore—designed to maintain precise gap between assemblies, provide electrical conductivity and deliver stable mechanical support. Tailored to client specifications, it eliminates the limitations of standard spacers and ensures long-term performance under thermal stress and vibration, making it essential for electronic devices, medical instruments and precision machinery where accurate spacing and conductivity are critical.
