M3 20mm Hexagonal Male-Female Standoffs Mounting Kit (10 Sets)

This mounting kit contains ten sets of M3 20mm hexagonal male-female standoffs complete with matching screws and nuts. It provides reliable vertical spacing and mechanical alignment for stacked circuit boards, sensor modules, and structural plates. It is ideal for students, makers, and robotics hobbyists building multi-layer embedded systems.

Fixed 20mm component separation

Each hexagonal spacer provides a fixed 20mm vertical clearance between mounted circuit boards or structural plates. This reliable spacing prevents unwanted electrical contact between layers while improving airflow and wiring management.

Male-female threaded stacking design

The M3 male-female threading allows direct vertical expansion and secure multi-tier stacking. It ensures rigid mechanical alignment across multi-board setups, sensor arrays, and robotics frames.

Complete fastener set

Every pack includes ten M3 20mm male-female standoffs, ten matching M3 6mm screws, and ten M3 nuts. This provides an all-in-one fastening solution without the need to source separate mounting hardware.

Broad prototyping and robotics compatibility

Designed for robotics chassis assembly, layered controller platforms, and modular sensor brackets. The hardware delivers dependable mechanical support for laboratory prototypes, maker projects, and educational builds.

Key hardware specifications

The standoffs feature an M3 thread with a 20mm body length, accompanied by 6mm screws and matching nuts. The total gross weight of the complete 10-set kit is 30g.
