Manufactured from brass with a clear zinc chromate finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff accepts an M3 x 0.5 threaded fastener. The overall length is 9 millimeters with a fully threaded interior at 9 millimeters thread depth, and the hex body measures 4.5 millimeters across the flats. Electronics assembly technicians, PCB assemblers, and field service engineers install these in control boards, industrial enclosures, and electronic assemblies where consistent board-to-surface standoff height is required.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric-threaded circuit board mounting applications in commercial and industrial electronics, HVAC control boards, electrical enclosures, and similar assemblies. The M3 x 0.5 thread size is a widely used metric standard in low-profile PCB mounting configurations. The brass base material provides good electrical conductivity and corrosion resistance, while the zinc plating adds additional surface protection in moderately demanding environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3 x 0.5 female thread, fully threaded to full 9 millimeter depth\u003c\/li\u003e\n  \u003cli\u003eHex body shape with 4.5 millimeter width across flats for wrench engagement\u003c\/li\u003e\n  \u003cli\u003eBrass construction with clear zinc chromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards\u003c\/li\u003e\n  \u003cli\u003eLength tolerance held to -0.13 to 0.13 millimeters for consistent board spacing\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 10 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install metric standoff for M3 x 0.5 threaded circuit board mounting applications in electronic assemblies and control enclosures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics assembly technicians or field service personnel. Power down and de-energize all circuits before installing or removing standoffs from any live control board or enclosure. Use an appropriately sized hex driver or wrench matched to the 4.5 millimeter across-flats hex body to avoid rounding the standoff. Follow applicable enclosure and equipment manufacturer torque guidelines when seating fasteners into the female thread.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 9 millimeters (approximately 0.354 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 9 millimeters (fully threaded)\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 millimeters (approximately 0.177 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.13 to 0.13 millimeters\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: 0.00344 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: MP417M03F21M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739332739378,"sku":"MP417M03F21M3","price":22.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fc684cde045c4d1faff9ecaafacd443.jpg?v=1788813249","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mp417m03f21m3-hex-board-standoff-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
