Machined from aluminum grade T3 and left uncoated with a bright finish, this spacer provides a rigid standoff between a PCB and a mounting surface or between stacked boards. The overall length is 2 mm, the outside diameter is 6 mm, and the inside diameter ranges from 3.2 to 3.6 mm. The length tolerance is -0.13 to 0.13 mm and the inside diameter tolerance is 0.000 to 0.270 mm. Electronics assembly technicians and PCB fabricators use this spacer to maintain precise board clearance and prevent electrical contact between layers or mounting hardware.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for use in control boards, power supply assemblies, and embedded electronics found across HVAC control modules, industrial equipment, and general electronics manufacturing. Its compact 2 mm profile makes it appropriate for tight PCB stack-ups where minimal standoff height is required. The metric M3 screw sizing is standard across a wide range of circuit board mounting configurations. The aluminum construction keeps weight minimal while providing reliable mechanical support in both residential and light commercial electronic assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded round body accepts M3 screws for straightforward PCB mounting\u003c\/li\u003e\n\u003cli\u003eAluminum grade T3 construction per QQ-A-225A Comp 2 fastener standard\u003c\/li\u003e\n\u003cli\u003e2 mm overall length suits low-profile PCB stack-up applications\u003c\/li\u003e\n\u003cli\u003e6 mm outside diameter with 3.2 to 3.6 mm inside diameter for M3 screw clearance\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains dimensional accuracy without added coating buildup\u003c\/li\u003e\n\u003cli\u003eTight length tolerance of -0.13 to 0.13 mm supports consistent board spacing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-build component for circuit board assemblies requiring M3 metric screw sizing and a female unthreaded round spacer configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians and PCB assembly professionals. Power down and discharge all capacitors in the target assembly before handling circuit boards or installing spacers. Use calibrated hand tools appropriate for M3 hardware to avoid over-torquing fasteners through the unthreaded spacer bore. Follow applicable IPC assembly standards for PCB standoff installation in the relevant equipment category.\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\u003eFor Thread Size\u003c\/strong\u003e: M3\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: 2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.2 to 3.6 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\u003eLength Tolerance\u003c\/strong\u003e: -0.13 to 0.13 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: 0.0008 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: MS1003M04F16D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51753996714290,"sku":"MS1003M04F16D","price":17.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0a405ceb63c0dd5c1dbdb7f5517a2d3_54225329-6fdc-4da1-9dbe-a08b4df23cd2.jpg?v=1788942690","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1003m04f16d-round-board-spacer-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
