10 Sets M3 * 30 Hexagonal Standoffs Mounting Kit

M3 30mm hexagonal male–female standoffs provide a practical structural solution for mounting circuit boards, sensor modules, and mechanical components in electronic assemblies. This hardware spacer set creates reliable vertical separation between stacked boards, improving airflow, cable routing, and mechanical stability. Designed for robotics platforms, prototyping frames, and embedded electronics, these threaded metal spacers simplify multi-layer construction while maintaining strong alignment between mounted components. The 10‑piece standoff kit includes matching screws and nuts, allowing secure fastening of development boards, sensor plates, and structural brackets in compact electronic or robotic builds.

Stable Multi‑Layer Mounting Structure

Each hexagonal spacer functions as a rigid support column for stacked electronics. The 30 mm height provides adequate clearance between PCB layers, enabling clean routing of wires, connectors, and sensor cables. This mechanical spacing hardware is particularly useful in robotics platforms and experimental electronics where multiple control boards, drivers, or sensing modules must be installed in vertical tiers. The hexagonal exterior also allows convenient tightening with standard tools, ensuring stable mounting and resistance to vibration during operation or movement.

Complete Fastening Set for Quick Assembly

Every spacer in this mounting hardware kit includes matching M3 screws and nuts, forming a complete fastening solution for electronics assembly. The threaded male–female structure allows simple stacking or extension when building layered mechanical frames or multi-level robot chassis. Such modular mounting hardware reduces installation time while maintaining precise alignment between boards and structural plates. Reliable threaded connections also support repeated assembly and disassembly during prototyping, testing, or system upgrades.

These threaded PCB spacers support a wide range of electronics projects requiring secure board separation and mechanical reinforcement. Common uses include robot chassis construction, sensor platform stacking, embedded controller mounting, and structural support for experimental prototypes. Reliable spacing hardware enables organized layouts, improved durability, and flexible mechanical design across robotics, DIY electronics, and engineering development projects.
