Machined from 18-8 and Grade 303 stainless steel with an anodized finish, this standoff meets the QQ-S-763 fastener standard. It features a 4-40 thread size, an overall length of 15\/16 inches (0.9375 inches), a body length of 3\/4 inches, and a hex width across flats of 1\/4 inch. Licensed electronics technicians, electrical contractors, and OEM assembly professionals install these in control boards, HVAC circuit board assemblies, and industrial enclosures.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for use in residential and commercial electronic assemblies where consistent board-to-board or board-to-chassis spacing is required. Common applications include HVAC control board mounting, industrial control panel PCB stacking, and enclosure-mounted electronics where vibration resistance and corrosion resistance are priorities. The stainless steel construction makes it appropriate for environments with moderate exposure to moisture or corrosive conditions. The hex body allows installation and removal with standard hex drivers or wrenches without marring surrounding surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 male-female thread configuration for secure PCB mounting and stacking\u003c\/li\u003e\n\u003cli\u003e18-8 and Grade 303 stainless steel construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eAnodized finish per QQ-S-763 fastener standard\u003c\/li\u003e\n\u003cli\u003eOverall length of 15\/16 inches with a 3\/4-inch body length and 3\/16-inch thread length\u003c\/li\u003e\n\u003cli\u003eHex body shape with 1\/4-inch width across flats for wrench or driver installation\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.005 to 0.005 inches for precise board spacing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 threaded male-female hex standoff for use in circuit board assemblies, control panels, and electronic enclosures requiring inch-system fasteners.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified electronics technicians or electricians during panel assembly or PCB service. Power down and de-energize all circuits before removing or installing circuit board hardware. Use an appropriately sized hex driver or nut driver matching the 1\/4-inch flats to avoid rounding the hex body. Follow applicable NEC requirements and equipment manufacturer guidelines when working inside electrical enclosures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male\/Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 15\/16 inches (0.9375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1\/4 inches (0.2500 inches)\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 \/ Grade 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-763\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 1443M09F16-440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51742779244850,"sku":"1443M09F16-440","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b33f982266436dcb29b7cf5c08c2d57.jpg?v=1788839347","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1443m09f16-440-hex-standoff-4-40-15-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
