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

M3 20mm hexagonal male–female standoffs provide a simple and reliable mechanical spacing solution for electronic assemblies. This hardware mounting kit is designed for securing circuit boards, sensor modules, and structural plates while maintaining precise vertical separation between layers. The threaded spacer design enables stable stacking of boards and brackets, making the hardware suitable for robotics frames, prototyping platforms, and embedded system installations. With integrated screw and nut accessories included in the package, this mechanical support set simplifies multi-layer electronics construction and improves structural rigidity in compact electronic builds.

Stable Multi‑Layer Board Spacing

Each hexagonal spacer provides a fixed 20mm separation between mounted components, allowing circuit boards, shields, or structural plates to be stacked safely without electrical contact. The male–female threaded configuration enables vertical expansion of assemblies while maintaining strong mechanical alignment. Such structural spacing hardware is widely used in robotics platforms, multi‑board embedded systems, and sensor arrays where consistent board clearance improves airflow, wiring management, and overall system reliability.

Complete Mounting Hardware Set

Every package includes ten threaded standoffs together with matching screws and nuts, forming a ready‑to‑use fastening solution for electronics projects. The included hardware eliminates the need to source additional fasteners when assembling development boards or mechanical frames. This integrated mounting kit supports efficient prototyping and mechanical installation for sensors, controller boards, and robotic chassis structures, ensuring stable attachment and convenient assembly during hardware development or educational builds.

Mechanical spacer hardware of this type is commonly used in robotics chassis construction, sensor mounting brackets, layered controller platforms, and general electronics prototyping. The threaded standoff design allows fast installation while maintaining reliable structural spacing between components, supporting organized wiring layouts and durable multi‑board assemblies in maker projects, laboratory prototypes, and educational engineering environments.
