Unique-Bargains M3 40+6mm Brass Hex Standoff Spacers 30pcs

SKU CH-FT21-NW6DE

Pack of 30 brass M3 hex standoffs with 40 mm female and 6 mm male threads for PCB mounting

  • Brass construction resists corrosion for reliable PCB mounting
  • M3 threads fit standard board spacing with 6mm male and 40mm female lengths
  • 46mm total height separates boards precisely in stacked assemblies
  • 2mm hex width allows secure tightening with common tools
  • 30-piece pack supplies enough spacers for multiple prototype builds

Brass M3 PCB spacers

These 30 brass hex standoffs create a 46mm separation between circuit boards and mounting surfaces. Each spacer combines a 6mm male thread with a 40mm female thread for secure stacking. The 5.2mm hex profile allows tool tightening without slippage. Gold-tone brass resists corrosion in enclosed assemblies.

For prototyping and permanent builds

Makers securing Raspberry Pi HATs, Arduino shields or custom PCBs to chassis plates will find the mixed-thread format convenient. Builds needing insulated standoffs, shorter stand-offs or a different thread pitch should select another hardware type. The fixed 46mm height suits only designs with that exact board-to-board clearance.

Under vibration and thermal cycling

Brass construction maintains clamping force across temperature swings better than nylon alternatives. The 150g pack weight reflects solid metal density that resists creep under sustained screw tension. Hex flats transmit installation torque cleanly, reducing the risk of rounded corners during repeated assembly and disassembly cycles.

Questions about this item

What M3 hardware do I need to secure these 46mm spacers?

You need M3 screws or bolts for the 6mm male thread and M3 nuts or threaded holes for the 40mm female thread.

Will these 5.2mm hex pillars fit the same M3 mounting pattern as my older brass standoffs?

Yes, the M3 thread size matches standard M3 patterns, so they align with existing M3 holes and fasteners.

How can I confirm the 30 pieces are all 46mm long after unpacking?

Measure each spacer end to end; every piece should read 46mm total with a 6mm male section and a 40mm female section.
