The M3 x 20mm Hex Spacer – Threaded Female is a durable mounting component used to maintain spacing and provide mechanical support between electronic or structural assemblies. It is widely used in PCB mounting, robotics, industrial electronics, embedded systems, and DIY hardware projects.
This spacer features female M3 threads on both ends and a hexagonal outer body that allows easy installation using standard hand tools. With a 20mm body length, it provides increased spacing for larger assemblies and better cable or airflow management between components.
