Machined from brass with a clear zinc chromate plating, this standoff meets ASTM B633 Type 1 and QQ-B-626 Comp 22 finish standards. The M3 x 0.5 internal thread runs the full 6 mm body length, providing solid thread engagement throughout. At 4.5 mm across flats, the hex body accepts a standard wrench or socket for secure installation and removal. Electronics assemblers, PCB technicians, and electricians use this fastener in control panels, enclosures, and circuit board assemblies.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for metric-threaded PCB mounting applications in both commercial and industrial electronics. The fully threaded 6 mm bore allows a mating male screw to engage the entire thread depth, maximizing pull-out strength in low-clearance board stacks. It is commonly installed in control board assemblies, power supply enclosures, and industrial equipment where repeatable board-to-board spacing is required. Its compact hex profile keeps the footprint tight in dense board layouts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM3 x 0.5 female thread, fully threaded through the 6 mm body length for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003eHex body shape with 4.5 mm width across flats for wrench installation and precise torque control\u003c\/li\u003e\n\u003cli\u003eBrass construction provides good conductivity and corrosion resistance in enclosed assemblies\u003c\/li\u003e\n\u003cli\u003eClear zinc chromate finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.13 to 0.13 mm supports consistent board-to-board spacing\u003c\/li\u003e\n\u003cli\u003eMetric measurement system for compatibility with M3-standard PCB hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with M3 x 0.5 metric male screws and threaded PCB mounting hardware in standard circuit board standoff applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians and electricians during board assembly or panel wiring. De-energize all circuits before servicing any control board or enclosure. Use a wrench or nut driver sized to 4.5 mm across flats to seat the standoff without over-torquing the brass body. Apply thread-locking compound only if specified by the board manufacturer, as excess compound in the bore can compromise thread engagement with the mating fastener.\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: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 6 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: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Clear Zinc Chromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM B633 Type 1, QQ-B-626 Comp 22\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: 0.00264 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: MP411M03F21M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743903908146,"sku":"MP411M03F21M3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2353e73baf67b144288e784736543efd.jpg?v=1788851101","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mp411m03f21m3-female-hex-standoff-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
