Machined from aluminum grade T3 per fastener standard QQ-A-225A Comp 2, this spacer delivers a lightweight, corrosion-resistant solution for precision board mounting. It accepts an M3 screw, measures 5 mm overall length, features a 6 mm outside diameter, and an inside diameter ranging from 3.2 mm to 3.6 mm. The uncoated bright finish keeps tolerances tight and surfaces clean for electrical assemblies where coating thickness would interfere with fit.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for electronics assembly and PCB mounting applications across industrial controls, HVAC control boards, lighting drivers, motor control panels, and general electrical enclosures. It is installed by electronics assemblers, industrial maintenance technicians, and field service engineers who require a reliable metric standoff in tight board layouts. The metric sizing makes it a direct fit in metric-dimensioned assemblies where M3 fastener patterns are standard.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded body accepts M3 screws for straightforward board-to-board or board-to-chassis standoff mounting\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\u003e5 mm overall length with a tight length tolerance of -0.13 mm to 0.13 mm for consistent stack height\u003c\/li\u003e\n\u003cli\u003e6 mm outside diameter with inside diameter ranging from 3.2 mm to 3.6 mm\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish eliminates coating buildup that could affect fit in close-tolerance assemblies\u003c\/li\u003e\n\u003cli\u003eRound body shape for uniform load distribution around the mounting hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with M3 screw fasteners in metric PCB and circuit board mounting assemblies requiring a female unthreaded round spacer with a 6 mm outside diameter and 5 mm standoff height.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics assemblers or qualified technicians working on de-energized equipment. Power down and discharge any capacitors in the assembly before handling PCBs or installing standoffs. Use calibrated torque-limited drivers appropriate for M3 fasteners to avoid cracking the board or deforming the spacer. Follow applicable IPC assembly standards and the equipment manufacturer guidelines for standoff placement and board support requirements.\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: 5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.13 mm to 0.13 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 mm to 3.6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0 mm to 0.27 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: 0.0012 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: MS1009M04F16D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51744472596786,"sku":"MS1009M04F16D","price":23.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0a405ceb63c0dd5c1dbdb7f5517a2d3_e7da6912-d00a-4646-a5de-b3f9a6b5fd9e.jpg?v=1788857003","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1009m04f16d-round-board-spacer-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
