M3 × 30 mm Brass Standoff Spacer (Female–Male)

M3 × 30 mm brass standoff spacers are precision hardware used to create a controlled gap between components in electronic assemblies and mechanical builds. This female–male variant features an M3 female thread on one end and an M3 male stud on the other, enabling quick, secure stacking of PCBs, modules, panels, and enclosures. Ideal for Arduino, Raspberry Pi, and other microcontroller-based projects, these standoffs provide robust mechanical support and maintain safe electrical clearance around voltage-sensitive circuits.

⚙️ Typical Applications

• Mounting and spacing PCBs in enclosures, test jigs, and control panels
• Stacking development boards, shields, HATs, and electronics modules (e.g., Arduino, Raspberry Pi, sensor boards)
• Providing clearance for components, connectors, heat sinks, and airflow
• Supporting covers, faceplates, displays, and mechanical subassemblies

🌟 Features & Benefits

• Precise spacing: Maintains consistent 30 mm separation for alignment and mechanical stability
• Durable brass construction: Excellent strength with natural corrosion resistance for long service life
• Electrical clearance: Creates safe spacing around traces and high-density circuitry (note: brass is conductive)
• Versatile mounting: Female–male format simplifies board stacking and panel mounting
• Good conductivity: Brass offers reliable electrical grounding paths where required

📐 Technical Specifications

• Thread size: M3 (standard 0.5 mm pitch)
• Length: 30 mm body spacing
• Type: Female (internal thread) to Male (external thread)
• Material: Solid brass
• Form factor: Commonly available in round, hex, and square bodies for tool engagement
• Use case: PCB mounting, module stacking, and general electronics/mechanical assembly

🧰 Installation Notes

• Hand-tighten or use appropriate tools on hex/square bodies to avoid over-torqueing threads
• Use with matching M3 screws, washers, and nuts as needed for your enclosure or PCB stack-up
• For electrical isolation, ensure spacing from conductive areas; the standoff itself is conductive

🔧 Versatility and Variants

Brass standoffs are available in multiple shapes (round, hex, square), lengths, and thread sizes to suit diverse mounting requirements. Whether you are building custom fixtures, assembling microcontroller projects, or integrating electronics modules into enclosures, these spacers deliver reliable support, alignment, and clearance.

✅ Summary

The M3 × 30 mm Female–Male Brass Standoff Spacer is a versatile, high-quality hardware component for precise PCB spacing, panel support, and stacked assemblies. Its robust construction, corrosion resistance, and universal M3 threading make it a dependable choice for both electronics engineers and hobbyists working with Arduino, Raspberry Pi, and other embedded systems.
