The part number **M2SBS-412-R2** generally refers to a specific type of **Standoff** or **Spacer** used in electronic hardware assemblies, specifically designed for mounting printed circuit boards (PCBs) or mechanical components. --- ### 1. Technical Specification Breakdown While part numbers can vary slightly by manufacturer, the nomenclature for this series typically follows these parameters: | Component Attribute | Specification | | :--- | :--- | | **Series** | M2SBS (Metric Self-Broaching Standoff) | | **Thread Size** | M2 (2.0 mm diameter) | | **Length (L)** | 12 mm | | **Material** | Usually Stainless Steel or Carbon Steel (R2 suffix indicates specific plating/revision) | | **Installation Type** | Press-fit / Self-broaching into non-ductile materials | ### 2. Physical Design and Function These parts are engineered to create a permanent, threaded attachment point in thin sheets of material where tapping a thread is not feasible. * **Self-Broaching Action:** The "SBS" designation indicates the part has a knurled or serrated shank. When pressed into a pre-drilled hole, it "cuts" or deforms the material to lock itself into place, preventing rotation. * **Clearance/Spacing:** Its primary role is to maintain a fixed distance (12mm) between two surfaces, such as a PCB and a metal chassis, to prevent electrical shorts and ensure proper airflow. ### 3. Application Use Cases 1. **PCBA Mounting:** Securing high-density circuit boards into server racks or telecommunication equipment. 2. **Thermal Management:** Elevating components to allow heatsinks or fans to operate effectively. 3. **Mechanical Structural Support:** Acting as a load-bearing pillar in multi-layered electronic enclosures. ### 4. Installation Requirements To ensure the mechanical integrity of the M2SBS-412-R2, the following conditions are typically required: ```yaml Installation_Parameters: Hole_Diameter: "Specific to substrate (usually slightly smaller than shank)" Substrate_Hardness: "Must be softer than the standoff material" Force_Required: "Controlled squeeze (Arbor press or hydraulic press)" Min_Sheet_Thickness: "Typically 1.0mm to 1.5mm" ``` ---
