The M3 x 25mm Hex Spacer – Threaded Female is a precision mounting component designed to create a fixed 25mm gap between electronic or mechanical assemblies. It is widely used in PCB mounting, robotics, industrial electronics, automation systems, and DIY hardware projects where secure spacing and structural support are required.
This spacer features female M3 threads on both ends and a hexagonal body that allows easy tightening using standard tools. Its longer 25mm body provides additional clearance for larger assemblies, cable management, airflow, and multi-layer PCB stacking.
