Hex Spacer M3x30 f/f (copper)

From the shop's description

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. 🔹 Specifications: Thread Type: M3 Internal (F/F) Spacer Length: 30mm Material: Copper Body Shape: Hexagonal Color: Gold-tone brass Corrosion Resistance: ✔️ Excellent Conductivity: ✔️ Thread Depth: ~6–8mm per end (typical) 🔹 Key Features: High-conductivity copper for EMI-sensitive applications Corrosion-resistant finish Precise M3 threading on both ends Easy installation and firm grip via hex shape Ideal for multi-layer circuit board configurations 🔹 Applications: PCB separation and leveling 3D printer electronics mounting Robotics and control boards Industrial and embedded projects CNC and IoT hardware builds
