Machined from aluminum alloy to the QQ-A-225A Comp 2 standard, Material Grade T3, this standoff features a fully threaded M3 x 0.5 internal thread running the full 21 mm body length. The hex body profile measures 4.5 mm across flats, allowing standard hex drivers and nut drivers to seat cleanly during installation. Its plain, bright uncoated finish suits general-purpose electronic assembly applications where anodizing or additional coating is not required. Electronics assemblers, board-level technicians, and OEM production staff are the typical installers.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for metric PCB stacking assemblies, chassis mounting applications, and control board installations where an M3 x 0.5 threaded interface is specified. The 21 mm overall length provides clearance for component clearance requirements or wire routing between stacked boards. Typical applications include industrial control panels, HVAC control board assemblies, electrical enclosures, and embedded electronics builds where consistent board-to-board or board-to-chassis standoff height is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFully threaded female M3 x 0.5 internal thread — 21 mm thread depth\u003c\/li\u003e\n\u003cli\u003eHex body shape, 4.5 mm width across flats — compatible with standard hex drivers\u003c\/li\u003e\n\u003cli\u003eAluminum construction to QQ-A-225A Comp 2, Material Grade T3\u003c\/li\u003e\n\u003cli\u003ePlain bright uncoated finish — suitable for general electronic assembly\u003c\/li\u003e\n\u003cli\u003eLength tolerance held to -0.13 to 0.13 mm for consistent stack height\u003c\/li\u003e\n\u003cli\u003eLightweight aluminum keeps assembly weight minimal in dense board layouts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a metric M3 x 0.5 female hex standoff for use in PCB stacking, chassis mounting, and control board assemblies where a 21 mm OAL aluminum standoff is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a hex driver or nut driver sized for a 4.5 mm across-flats hex body. Power down all equipment and discharge any stored energy before working inside electrical enclosures or on control boards. Do not over-torque aluminum standoffs, as the material is susceptible to thread stripping; hand-tighten and snug with a driver only. Follow applicable IPC assembly standards and the equipment manufacturer's torque guidelines for M3 fasteners.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3 x 0.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 21 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 21 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.5 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\u003eMaterial\u003c\/strong\u003e: Aluminum, Grade T3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain, Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-A-225A Comp 2\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: 0.00224 pounds\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: MP441M06F16M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51733292450098,"sku":"MP441M06F16M3","price":30.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42f6c212976aa439d0399aeeef348c0a_cc622f1e-4e73-430d-bba4-e219205ada68.jpg?v=1788753678","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mp441m06f16m3-hex-standoff-m3-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
