Machined from 303 stainless steel with a bright uncoated finish, this standoff meets the QQ-S-763 federal specification for stainless steel fasteners. It features an M3x0.5 thread on the male end and a corresponding M3x0.5 female threaded bore on the opposite end. The hexagonal body measures 4.5 mm across flats, allowing secure engagement with a standard wrench or hex driver. Overall length is 20.76 mm, with a body length of 16.00 mm. Electronics technicians and electrical panel assemblers install these as part of PCB mounting hardware stacks in control boards and enclosures.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric PCB mounting applications in industrial control panels, HVAC control board assemblies, electrical enclosures, and similar electronic equipment requiring a rigid, corrosion-resistant spacer. The male-female configuration allows multiple standoffs to be stacked or used in single-tier board mounting layouts. The stainless steel construction makes it appropriate for environments where corrosion resistance is a priority, including light washdown or high-humidity service conditions typical in HVAC and pool control equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3x0.5 male thread on one end and M3x0.5 female threaded bore on the opposite end for stacking versatility\u003c\/li\u003e\n  \u003cli\u003e303 stainless steel construction with bright uncoated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHexagonal body at 4.5 mm across flats for positive wrench engagement during installation\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-763 federal specification for stainless steel fastener material standards\u003c\/li\u003e\n  \u003cli\u003eOverall length of 20.76 mm with a length tolerance of -0.150 to 0.150 mm for consistent board spacing\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31161816 for procurement system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a metric M3x0.5 male-female hex standoff for use in PCB mounting applications requiring QQ-S-763 compliant stainless steel fasteners and a 4.5 mm hex body profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics technicians or licensed electricians during panel assembly or control board service. De-energize all circuits fully before removing or installing PCB standoffs. Use an appropriately sized metric wrench or hex driver on the 4.5 mm flats to avoid rounding the body. Do not overtighten; standoffs should be snug against the mounting surface without distorting the PCB substrate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3x0.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male and Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20.76 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 16.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 4.76 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 6.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.150 to 0.150 mm\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\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 303 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\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: 0.00624 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\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: MMF1323M09F16M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739870953778,"sku":"MMF1323M09F16M3","price":21.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba7ad5e9b9bf9dbcf946f2b415f5ea93_bfc929c5-2269-4849-afc4-c315a8b2177f.jpg?v=1788819874","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1323m09f16m3-hex-standoff-m3x0-5","provider":"Voomi Supply","version":"1.0","type":"link"}
