Manufactured from aluminum grade T3 and conforming to fastener standard QQ-A-225A Comp 2, this spacer delivers consistent dimensional accuracy in tight-tolerance assemblies. It accepts an M3 screw, measures 3 mm overall length, features an inside diameter range of 3.2 to 3.6 mm, and has a 6 mm outside diameter. The bright uncoated finish keeps the aluminum bare, which suits applications where surface treatment is applied after assembly or where electrical continuity through the hardware is required.\u003c\/p\u003e\n\u003cp\u003eThis spacer is used in PCB mounting applications across industrial controls, HVAC control boards, electrical enclosures, and similar electronic assemblies where metric hardware is specified. The M3 thread size and compact 3 mm standoff height make it suitable for low-profile board stacking or chassis-mount configurations. Electronics technicians, control board assemblers, and field service technicians installing replacement control boards commonly use hardware of this type when servicing or building metric-fastener assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded body accepts M3 screws for straightforward PCB mounting\u003c\/li\u003e\n  \u003cli\u003eAluminum grade T3 construction per QQ-A-225A Comp 2 for consistent material properties\u003c\/li\u003e\n  \u003cli\u003e3 mm overall length with a tight length tolerance of -0.13 to 0.13 mm\u003c\/li\u003e\n  \u003cli\u003e6 mm outside diameter with inside diameter range of 3.2 to 3.6 mm\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating to interfere with downstream surface treatments\u003c\/li\u003e\n  \u003cli\u003eRound body shape for standard clearance-hole PCB footprints\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a metric M3 round circuit board spacer for use in PCB assemblies and electronic enclosures requiring a female unthreaded aluminum standoff with a 3 mm overall length and 6 mm outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or control board service personnel. De-energize all circuits and discharge any capacitors before handling PCBs or installing board hardware. Use appropriately sized M3 fasteners and avoid overtightening, which can deform the aluminum spacer body or crack the PCB substrate. Follow applicable electrical codes and equipment manufacturer guidelines when servicing control boards in HVAC, industrial, or electrical enclosure applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 3 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: 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\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: 0.00096 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: MS1005M04F16D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51731628196146,"sku":"MS1005M04F16D","price":32.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0a405ceb63c0dd5c1dbdb7f5517a2d3_6bdab9c4-d7c5-408b-843a-3fe9ae8e64f0.jpg?v=1788733333","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1005m04f16d-round-board-spacer-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
