Machined from Grade 18-8 303 stainless steel with a passivated finish, this standoff resists corrosion and meets QQ-S-763 federal specifications. The M5 x 0.8 thread runs on both ends, with an overall length of 25 mm and a hex body width across flats of 8 mm. The passivated surface treatment removes free iron from the steel surface, extending service life in humid or industrial environments. Weighing 0.19 pounds, it is suited for light-duty board mounting applications where dimensional consistency is critical.\u003c\/p\u003e\u003cp\u003eThis standoff is used in electronic control panel assemblies, circuit board stacking configurations, and enclosure builds across industrial, HVAC controls, and electrical panel applications. Installers and assemblers use male-male standoffs when both mating surfaces require a threaded fastener interface. The hex body shape allows standard wrench or nut driver engagement for consistent torque application without slipping. Its metric M5 x 0.8 thread pitch makes it appropriate for metric-threaded PCB hardware and panel assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM5 x 0.8 male thread on both ends for dual-threaded panel or board mounting\u003c\/li\u003e\n\u003cli\u003e25 mm overall body length with a length tolerance of -0.15 mm to +0.15 mm for precise spacing\u003c\/li\u003e\n\u003cli\u003e8 mm width across flats allows engagement with standard hex drivers and wrenches\u003c\/li\u003e\n\u003cli\u003eGrade 18-8 303 stainless steel construction with passivated finish per QQ-S-763\u003c\/li\u003e\n\u003cli\u003eThread length of 9 mm to 10 mm on each end provides full thread engagement\u003c\/li\u003e\n\u003cli\u003eHex body shape prevents rotation during installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for metric M5 x 0.8 threaded circuit board and panel standoff applications in electronic assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics assemblers, panel builders, or electricians working on control enclosures. Power down and de-energize all boards and panels before installing or removing standoffs. Use a calibrated hex driver or wrench sized for 8 mm across flats to avoid rounding the hex body. Follow applicable assembly standards and enclosure codes when integrating into listed control panels.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M5 x 0.8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male-Male\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: 9 mm to 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.15 mm to +0.15 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 8 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\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: 0.19 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: MMX1645M09MSC-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51727086551346,"sku":"MMX1645M09MSC-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84357611908f27e2258afcb9d4da0d3c_3cd97742-37c3-4720-86ee-fe08a42a8e56.jpg?v=1788673076","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmx1645m09msc-1-hex-standoff-m5x0-8","provider":"Voomi Supply","version":"1.0","type":"link"}
