50 pieces included Built to last: Made from brass for strength and corrosion resistance, delivering a long service life in electronics assemblies. Specifications Thread size: M2 Male thread length: 3 mm Hex head design for easy installation Key benefits Reliable spacing: Maintains consistent gaps between boards to keep assemblies organized and aligned. Short circuit prevention: Provides separation to help prevent motherboard or circuit board shorts. Improved cooling: Creates airflow space between boards, supporting better heat dissipation. Easy installation: Hex head allows tool assisted tightening for quick, secure fitting. What makes this stand out Durable brass construction offers strength and corrosion resistance in various environments. Includes a generous quantity (50 pcs) for bulk projects or multiple builds. Specifically designed for M2 threaded components, with a compact 3 mm thread depth to fit tight electronics enclosures. Applications and use scenarios Electronics enclosures: Mount a PCB inside a case while keeping a safe gap from the chassis and other components. Computer and motherboard mounting: Space a motherboard or similar boards from a case wall or mounting plate to promote airflow and reduce contact points. DIY and robotics projects: Use as spacers between control boards, sensor boards, and motor controllers to maintain organization and prevent shorts. Compatibility and suitability Suitable for applications requiring M2 threading and compact spacers with a hex head. Ideal for mounting between circuit boards and machine boards in electronics, PC builds, and industrial equipment.
