Hex Spacer M3x30 f/f (copper)

The M3x30mm Female-Female Hex Spacer is a high-quality, durable standoff component made from solid copper with internal M3 threads on both ends. It is used to securely space and mount printed circuit boards (PCBs), mechanical parts, or modular electronics.

With a generous 30mm length, this spacer is ideal for stacking boards that require more clearance—such as for connectors, heat sinks, or moving components—while its hexagonal shape allows for easy tightening using a wrench or pliers.
