What you get Pack of 50 female brass standoff spacers with M2 (2.0 mm) internal threads. Length options range from 3 mm up to 30 mm (example size included: M2 x 22 mm). Key benefits — why you need these Reliable spacing and secure fastening: provide stable separation between components and clean, repeatable M2 threaded connections. Durable and corrosion-resistant: solid brass construction resists rust and maintains mechanical and electrical properties over time. Versatile and compatible: M2 internal thread fits standard M2 screws and hardware commonly used in electronics and small mechanical assemblies. What makes these stand out Female M2 threading simplifies assembly by allowing screws to engage directly into the spacer for stacked or mounted configurations. Wide length range (3–30 mm) covers many spacing needs without having to source multiple part types. Pack quantity of 50 keeps spare parts on hand for production, repairs, or prototyping. Features and performance Material: brass — good mechanical durability and electrical conductivity when metal standoffs are preferred. Thread: M2 (2 mm) internal thread for compatibility with M2 machine screws and bolts. Lengths available: from 3 mm through 30 mm; example included M2 x 22 mm for reference. Shape: round standoff spacer designed for easy installation and stable support. Typical applications Electronics assembly: separate and secure PCBs in enclosures, stack multiple boards, or mount daughterboards. Prototyping and repairs: use for hobby electronics, development boards, drones, and small robotics where consistent spacing and reliable threaded connections are needed. Mechanical and panel mounting: attach panels, displays, or sensors with precise spacing and a neat finished appearance. Practical notes Ensure M2 screw length and head type are appropriate for the chosen spacer length to achieve correct engagement. Brass is conductive — use insulating washers or non-metallic spacers where electrical isolation is required.
