HGLRC M3 to M2 Adapter Rivets / Hollow Grommets (30 Pcs)

The HGLRC M3 to M2 Adapter Grommets allow drone builders to cleanly mount flight controllers, ESCs, and VTXs with oversized M3 mounting holes onto standard M2 stack hardware. Acting as both a size step-down and a soft mechanical buffer, these hollow rivets isolate sensitive flight controller gyros from high-frequency frame and motor noise.

Key features

• Converts M3 (3 mm) PCB mounting holes to securely fit M2 (2 mm) screws and standoffs.
• Provides essential vibration dampening to filter out noise before it reaches the IMU, improving PID loop performance.
• Prevents direct rigid contact between metal screws and the circuit board, reducing the risk of trace damage in a crash.
• Generous 30-piece pack covers multiple quadcopter builds and leaves spares for repairs.

Specifications

• Board Hole Fit: M3 (3 mm)
• Hardware Fit: M2 (2 mm)
• Quantity: 30 pieces

Ideal for adapting 20x20mm stacks that feature M3 holes to lighter M2 hardware, or retrofitting older 30.5x30.5mm electronics into modern micro and cinewhoop frames.
