Machined from aluminum grade T3 and conforming to fastener standard QQ-A-225A Comp 2, this spacer accepts an M4 screw and delivers a consistent 6 mm overall length. The bore accommodates an inside diameter range of 4.2 to 4.8 mm, with an outside diameter of 6 mm. The bright, uncoated finish leaves the aluminum surface bare, making it suitable for applications where conductivity or minimal surface interference is acceptable. Electronics assembly technicians and field service professionals working on control boards in HVAC, electrical, and industrial equipment will encounter this style of spacer in standard PCB mounting configurations.\u003c\/p\u003e\u003cp\u003eThis spacer is used in electronic subassembly work wherever an M4-compatible standoff is required to separate circuit boards from enclosure bases, DIN-rail mounted controls, or stacked PCB assemblies. Common applications include control board mounting in residential and light commercial HVAC equipment, electrical panel subassemblies, and general electronics manufacturing or repair. Its metric dimensions make it appropriate for equipment designed to metric fastener standards. The unthreaded female body accepts a pass-through or threaded fastener from above, providing a clean, rigid mount point.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded round body accepts M4 screws for straightforward PCB standoff mounting\u003c\/li\u003e\n\u003cli\u003e6 mm overall length with a tight length tolerance of -0.13 to 0.13 mm for consistent board spacing\u003c\/li\u003e\n\u003cli\u003eInside diameter range of 4.2 to 4.8 mm accommodates standard M4 fastener shanks\u003c\/li\u003e\n\u003cli\u003e6 mm outside diameter in a compact round profile minimizes board footprint\u003c\/li\u003e\n\u003cli\u003eAluminum grade T3 construction per QQ-A-225A Comp 2 for lightweight, corrosion-resistant performance\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating thickness to account for in tight-tolerance assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or assembly component for circuit board mounting applications requiring an M4 metric screw size and a 6 mm standoff height in a round aluminum spacer configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics assembly technicians or field service personnel working on control board subassemblies. Power down and de-energize all circuits before handling or replacing circuit board hardware. Fasten to the recommended M4 torque specification for the host assembly as defined by the equipment manufacturer — do not over-tighten, as aluminum spacers can deform under excessive clamping load. Follow applicable IPC assembly standards and the host equipment manufacturer guidelines when integrating spacers into PCB mounting schemes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: T3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-A-225A Comp 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: M4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.13 to 0.13 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.2 to 4.8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.270 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00136 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ELECTRO HARDWARE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MS1011M04F16F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51732546781490,"sku":"MS1011M04F16F","price":17.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0a405ceb63c0dd5c1dbdb7f5517a2d3_66cab597-5f14-48d4-bf7f-3189b873153d.jpg?v=1788744300","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1011m04f16f-round-board-spacer-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
