Threaded M3 x 0.5 on both ends, this standoff provides a secure mechanical connection point without the need for separate fasteners on each side. The hexagonal body measures 5 mm across flats, allowing standard hex tools to drive or hold it during installation. Overall length is 25 mm, with a 25 mm body length and thread lengths of 5 mm and 6 mm per end. Machined from Grade 18-8 303 stainless steel with a passivated finish, it resists corrosion in moderately harsh service environments. Intended for use by electronics technicians, industrial maintenance personnel, and control panel fabricators.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for PCB mounting applications in control panels, industrial enclosures, HVAC control boards, and electronic assemblies requiring a metric fastener profile. The M3 x 0.5 thread size is a common metric pitch used widely in light-duty electronic hardware. The passivated stainless steel construction makes it appropriate for environments where mild exposure to moisture or chemicals is a concern. It meets the QQ-S-763 federal specification for stainless steel fasteners, which is relevant in applications where material traceability or specification compliance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-male threaded on both ends for direct board-to-board or board-to-panel mounting\u003c\/li\u003e\n  \u003cli\u003eM3 x 0.5 thread size with 25 mm overall length and hex body for wrench engagement\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 303 stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePassivated finish meets QQ-S-763 federal fastener specification\u003c\/li\u003e\n  \u003cli\u003e5 mm hex width across flats accommodates standard metric hex tooling\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of -0.150 mm to 0.150 mm for consistent stack height\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard metric M3 x 0.5 male-male hex standoff suitable for circuit board mounting and panel assembly applications where this thread size and overall length are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or control panel fabricators using a standard metric hex wrench or nut driver sized for 5 mm across flats. Always de-energize any board or panel assembly completely before installing or removing standoffs. Avoid overtightening, as excessive torque on small-diameter metric threads can strip the thread or crack PCB mounting holes. Verify thread engagement depth against the mating component specification before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male-Male\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: 25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 5 mm and 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel, Grade 18-8 303\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Passivated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.150 mm to 0.150 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-763\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: 0.18 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: MMX1445M09-MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51755197464882,"sku":"MMX1445M09-MSC","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84357611908f27e2258afcb9d4da0d3c_83cdb231-8a88-4120-875a-bed5d6c3263d.jpg?v=1788952071","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmx1445m09-msc-hex-standoff-m3-x-0-5-25mm","provider":"Voomi Supply","version":"1.0","type":"link"}
