PCB Standoff Spacer Kit (M3, 120pcs)

PCB Standoff Spacer Kit (M3, 120pcs)

120-piece M3 brass standoff kit — male-female standoffs in 6mm, 8mm, 10mm, and 12mm lengths, plus matching M3 screws and nuts. Essential for mounting PCBs and development boards in enclosures without short-circuiting the bottom of the board.

Key Specifications

• Thread: M3
• Lengths: 6mm, 8mm, 10mm, 12mm
• Includes: Male-female standoffs + M3 screws + M3 nuts
• Material: Brass (conductive — use plastic washers if needed for isolation)
• Total: 120 pieces

Common Use Cases

Mounting Arduino Uno (4 × M3 holes), Raspberry Pi (4 × M2.5 holes — use M3 with care), ESP32 carrier boards, and relay modules inside project enclosures. Brass standoffs conduct electricity — if your enclosure is metal, ensure PCB ground planes do not create unintended shorts through the standoffs.
